About Our Frames & Lenses
a) Standard metal is generally lightweight. Most metal frames are usually composed of a nickel/steel alloy.
b) Stainless steel is lightweight and corrosion resistant.
c) Titanium frames are hypoallergenic, the lightest of metals, and are superior in resisting corrosion. Titanium frames are the best choice for anyone that has experienced frame peeling in the past or whose frame has turned green in color around the nose pads.
d) Flexible or memory metal frames are made of a titanium alloy which allow for extreme flexing. Frames made of this type of material are best in durability and require minimal adjustments.
Plastic frames are mainly composed of a zyl material which makes these frames a nice lightweight choice. Plastic frames usually have no nose pads which may appeal to those who take on and off their glasses frequently.
3. Rimless and Semi-rimless:
Rimless consists of no frame on the front of the glasses. The glasses are supported by either metal or plastic temples, “frame arms”, which are drilled into the lenses. Semi-rimless implies half the glasses are supported with a frame and the other half (usually the bottom) is without a frame.
4. Spring hinge/Flexible hinge:
Spring hinges can be used in all types of frame materials. These pieces allow frames to flex where the temples “frame arms” meet the frame front. This feature helps relieve stress from everyday wear and tear.

COMPUTER/EXTENDED RANGE OFFICE LENS CATEGORY:
A lens that facilitates reading from a screen and that reduces eyestrain Using a computer makes specific demands on the body and its movements. That is why Computer/Extended Range Reading Lens was developed. Scientific research has shown that working on a screen can cause musculoskeletal disorders as well as heighten stress. While reading from a screen does not lead to eye disease, it can reveal untreated or poorly corrected visual deficiencies. It can also be the source of significant eyestrain. Computer Vision Syndrome (CVS) is a growing problem. Over 14% of patients scheduling an eye exam complain of CVS, the complex of eye and vision problems associated with extended computer use. Yet standard eyeglasses aren’t designed for computer use. They often cause wearers to squint or adjust their heads in an effort to see the monitor, keyboard and objects on the desk. This is especially true of presbyopes. Computer Lenses can provide you with clear vision out to 7 feet. Mid-range vision will vary depending upon prescription.
Occupational Lenses do not offer a clear view of objects beyond SEVEN feet away. They should never be used while driving or for other activities that require clear distance vision.

Cameras of the future: heart researchers create revolutionary photographic technique (UK)
"Scientists funded by the Biotechnology and Biological Sciences Research Council and the British Heart Foundation at the University of Oxford have developed a revolutionary way of capturing a high-resolution still image alongside very high-speed video - a new technology that is attractive for science, industry and consumer sectors alike. By combining off-the-shelf technologies found in standard cameras and digital movie projectors they have successfully created a tool that will transform many forms of detailed scientific imaging and could provide access to high-speed video with high-resolution still images from the same camera at a price suitable for the consumer market. This could have everyday applications for everything from CCTV to sports photography and is already attracting interest from the scientific imaging sector where the ability to capture very high quality still images that correspond exactly to very high speed video is extremely desirable and currently very expensive to achieve. The technology has been patented by Isis Innovation, the University of Oxford's technology transfer office, which provided seed funding for this development and welcomes contact from industry partners to take the technology to market. The research is published in Nature Methods"


Have you ever thought about what resolution corresponds to the pixel on the camera that our view has on you? Can the most powerful camera in the world match the structure of the human eye? And why do the camera and our eyes see the world in a different way? Let us try to find this together in this article.
How many megapixels does the human eye have?
The human retina has about 5 million color receptors, which is only 5 megapixels when translated into a pixel language. Not the most advanced display compared to modern devices, right?
Nevertheless, the human eye has about one hundred million monochrome receptors that determine the creation of a complete image of the surrounding space by the device that analyzes the incoming information – the brain. In addition, unlike the camera, the human organs of vision do not receive information statically but in motion, forming a common panoramic image that is 576 megapixels. Well, but this result is already inspiring!
Which animals have the best view?
Despite the complex system of the human vision device, which achieves an impressive 576 megapixel result, this number is not considered a limit in nature. The most complex visual system among all living things on planet Earth is the so-called peacock shrimp (lysiosquillina glabriuscula), which lives off the coast of Australia. According to research, these amazing creatures have outstanding eyesight, which in many ways surpasses all human optical systems.
Lysiosquillina glabriuscula has the unique ability to see the world in polarized light. In other words, shrimp can unknowingly use the same advanced 3D technologies that modern Hollywood experts use to create special effects for blockbusters. Zoologists believe that the function of such a vision can be used during the mating season or simply during communication between mantis shrimp.
What exactly can these sea creatures see with their unique eyes? Researchers believe that the vision of peacock shrimp can detect circularly polarized light that is invisible to the human eye and can be observed in the laboratory using special glasses with polarizers.
See also: Create a camera that can take pictures from a distance of 45 kilometers
In addition to shrimp, flies have one of the most perfect views in nature. It is assumed that the frame rate in the eyes of these insects is many times higher than that of human indicators. The frequency of image changes in flies is thus about 300 images per minute, while this number is only 24 images in humans.
The unique visual system of the fly has about 3.5 thousand small hexahedral facets, each of which can capture only the very meager details of the image. Thanks to such an arrangement of the eye, the fly can immediately navigate in space, which makes it so elusive for a running shoe.
What does the most powerful camera in the world look like?
The most powerful camera in the world is rightly a 3.2-gigapixel camera, which was developed as part of the construction of the Large Synoptic Research Telescope in Chile. The developers believe that the launch of the world's most powerful camera will take place very soon – in 2022. The huge camera weighs about 3 tons and has the dimensions of a small car. According to calculations, the telescope is actively used for 10 years, with the telescope camera taking about 800 images of the sky in the highest resolution. Scientists hope that the use of such a telescope will help humanity to know the universe better than ever before.
Do you believe that it is ever possible to develop a device that surpasses the human eye in every way? Let's try to discuss this issue in our telegram chat or on the Hi-News channel in Yandex.Zen.

PhotoMesh seamlessly combines oblique and nadir photographs with both aerial and terrestrial LiDAR data, automatically converting them into high-resolution, textured 3D mesh models (3DML). This fusion not only enhances the relative and absolute accuracy of the models but also reduces occlusions and improves the overall quality of 3D meshes. This article delves into the advantages of combining these two technologies, the data processing workflow within Skyline PhotoMesh, the role of LiDAR classification, and future directions in integrating imagery and LiDAR data. More about: Building a project with LiDAR data and Adding LiDAR and trajectory data >
In this article:
- Comparing the two technologies
- Data ingestion and processing workflow in Skyline PhotoMesh
- LiDAR classification
- Embedding the 3D textured mesh with attribution and semantic qualities
- Future directions in data integration
Comparing LiDAR and Photogrammetry
- Canopy Penetration (Multiple Returns): LiDAR emits laser pulses that penetrate vegetation canopies and measure the ground surface beneath, thanks to its ability to capture multiple returns from each pulse—first from the canopy top and then from subsequent layers down to the ground. This feature proves invaluable in forestry and topographic mapping for accurately modeling terrain underneath vegetation.
- Classification and Feature Extraction: LiDAR is highly suited for automatic classification, leveraging distinct data characteristics to distinguish accurately between surface types. It captures precise 3D coordinates within dense point clouds, essential for detailed identification and classification of features. Additionally, the variation in intensity of reflected light, corresponding to different materials such as vegetation, asphalt, and buildings, enriches the data's classification potential. Geometric details in the point clouds, including feature shape and texture, further refine its analytical capabilities. Together, these attributes enable LiDAR to be used in differentiating between and classifying a broad range of environmental and man-made features.
Efficiency in Narrow Scenes: LiDAR requires only a single ray to range and measure a feature, making it particularly effective in narrow or constrained environments (e.g., power lines, pipelines, and urban canyons) where photogrammetry might struggle due to the need for multiple photographic angles.
High Accuracy and Consistent Point Density: LiDAR is known for its high level of accuracy, providing precise measurements of distance based on the time it takes for a laser pulse to return after hitting a surface. This accuracy is consistent across all points, regardless of the texture or color of the surfaces, ensuring a uniform point density and reliable data for analysis.
Operational Flexibility: Unlike photogrammetry, LiDAR is not dependent on ambient light conditions. It can operate in complete darkness (nighttime) or under variable lighting conditions, offering flexibility in planning survey missions.
Lack of Color Information: Standard LiDAR sensors capture only the intensity of the returned light, which does not include color (RGB) information. This means that LiDAR datasets alone do not provide visual or color details about the surfaces.
Lower Spatial Resolution: While LiDAR provides highly accurate distance measurements, the spatial resolution (the density of points per square meter) might be lower compared to high-density aerial photogrammetry. For instance, high-density aerial LiDAR might achieve 50 points per square meter, whereas photogrammetry can achieve much finer resolutions, essential for detailed surface modeling.
Operational Complexity: Operating a LiDAR system, particularly from aerial platforms, requires careful planning and precise calibration of GPS and IMU (Inertial Measurement Units) to ensure data accuracy. These systems are sensitive to flying conditions and require optimal conditions to perform best, which can make LiDAR surveys more complex and potentially more costly to execute compared to simple photogrammetric methods.
- Ease of Entry and User Friendly Operation: Photogrammetry is known for its accessible entry point, making it an attractive option for newcomers in fields like surveying and mapping. Users can capture photos with standard cameras or drones and its user-friendly interface and software solutions allow individuals to quickly get started with data capture.
- Robustness in Varied Conditions: Unlike some other remote sensing technologies, photogrammetry is less sensitive to ideal flying conditions or the availability of high-end GPS (Global Positioning System) and IMU (Inertial Measurement Unit) equipment. It often relies on ground control points, which provide reference information for accurate data processing.
- Multispectral Capability: Photogrammetry has the potential to work with multispectral data, including Near-Infrared (NIR) and thermal imagery. This enables users to capture and analyze a broader range of information beyond visible light, useful in various applications like agriculture and environmental monitoring.
- Realistic Texture: One of the strengths of photogrammetry is its ability to create 3D models with realistic textures. By incorporating RGB (Red, Green, Blue) pixel data from photos, it produces visually accurate representations of objects and surfaces.
- High Resolution: Photogrammetry can achieve high-resolution outputs. For instance, a Ground Sampling Distance (GSD) as fine as 5 centimeters translates to 400 pixels per square meter. This level of detail is valuable in applications requiring precise mapping and measurement.
- Single Return: Photogrammetry provides a single return or perspective of the captured scene. This means it can only model what is directly visible in the images. Objects or surfaces obscured from view are not included in the final model, limiting its effectiveness in scenarios with occlusions or hidden features.
- Multiple Perspectives Required: To accurately reconstruct objects and features, photogrammetry typically requires at least two perspectives (images) of each correlated feature. This necessity for multiple viewpoints can be challenging in environments with restricted space or limited access.
- Correlation Challenges: Photogrammetry relies on correlating features across images, which can introduce accuracy biases. Triangulation and feature matching are critical steps, and their effectiveness can be reduced in cases of low-texture surfaces, low-quality correlation, or lower data density, leading to less accurate results.
Data Ingestion and Processing Workflow in PhotoMesh
Importing Photos and LiDAR Data
- Imagery Requirements: Photos must be in JPG or TIF format and include exterior and interior orientation metadata.
- LiDAR Data Compatibility: Supports LAS, LAZ, and e57 formats. Incorporating trajectory information is beneficial for enhancing mesh surface normal calculation.
Aerotriangulation and Photo-LiDAR Alignment
- Aerotriangulation Process: PhotoMesh automatically extracts tie points from the photos and performs a full Bundle Block Adjustment.
- LiDAR Integration: PhotoMesh extracts control points from LiDAR intensity data, enabling the precise alignment of photo blocks with the underlying LiDAR geometry for seamless integration.
Merging Geometric Data and Textures
- 3D Reconstruction: Combines the image-based point cloud with LiDAR data to form a unified geometric source which serves as the basis for the mesh model.
This process includes linear feature extraction (edge matching) and pixel-level detail detection.
- Texture Application: Applies textures to the mesh model by evaluating the highest image resolution, ensuring alignment is perpendicular to the mesh triangle normal, and optimizing for color balance.
LiDAR Classification serves multiple purposes, including the removal of unwanted objects from the LiDAR data, which in turn eliminates them from the final 3D mesh (e.g., vehicles, power lines, vegetation). Additionally, it plays a potential role in guiding the 3D reconstruction process by influencing triangle count and edge extraction based on the nature of the features being modeled.
The fusion of LiDAR's classification capabilities with the mesh model's attribute information and semantic qualities is pivotal in creating a smart 3D mesh model.
Embedding Attribution and Semantic Qualities
The 3D mesh models, can be classified in TerraExplorer Pro using classification polygons containing attribute data relevant to the mesh layer. Classification enables you to categorize different areas of the layer (e.g., based on building type: residential, commercial, or industrial). This classification can then be used to visually distinguish the different areas (e.g., by applying a different color to each category) and to perform spatial and attribute queries on the feature layer that is classifying the mesh layer.
Future Directions in Data Integration
- Expanded Sensor Integration: Integration of aerial Imagery and LiDAR with drone-based and mobile sensors.
- Enhanced Co-Registration Automation: Improving the automatic alignment of LiDAR and photographic data, streamlining the process to ensure a seamless and accurate fusion of diverse datasets.
- Innovative Sensor Applications: Addition of specialized sensors, like thermal imaging combined with LiDAR, to enable nighttime and low-visibility 3D modeling. This initiative will expand the capabilities and applications of 3D modeling by embracing a broader spectrum of data collection technologies.

Ccd Microscope Camera are mechanical devices used for viewing materials and items so minute in size that they are undetected by the naked eye. The procedure carried out with such an instrument, called Microscopy, utilizes the combined schools of optical science and light reflection, controlled and manipulated through lenses, to study small things at close quarters.
The fundamental microscope includes several complex and interrelated parts: a cylinder that supplies a required space of air in between the ocular lens (eye piece) located at the leading and the unbiased lens fixed at the bottom, hovering near to a stage consisting of an optical assembly on a turning arm and a focused hole through which a light shines from a solid U-shaped stand below. Magnifying worths for the ocular range through X5, X10, to X20, while the values for the unbiased lens has a broader period: X5, X10, X20, X40, x100, and x80. These worths provide the observer with a spectrum of possible distance orientations and degrees of sharpness as are required for seeing and analysis.
Several various kinds of microscopes exist, each having particular features:
Optical Microscope: The very first produced. The optical microscope has a couple of lenses that work to expand and boost images put in between the light source and the lower-most lens.
Simple Optical Microscope-- utilizes one lens, the convex lens, in the magnifying procedure. This type of microscope was used by Anton Van Leeuwenhoek during the late-sixteen and early-seventeenth centuries, around the time that the microscopic lense was developed.
Compound Optical Microscope-- has 2 lenses, one for the eyepiece to serve the ocular perspective and among brief focal length for unbiased viewpoint. Multiple lenses work to lessen both spherical and chromatic aberrations so that the view is unobstructed and uncorrupted.
Stereo Microscope: This is also known as the Dissecting Microscope, and more info utilizes 2 different optical shafts (for both eyes) to create a three-dimensional image of the things through two a little different viewpoints. Inverted Microscope: This kind of microscopic lense views objects from an inverted position than that of regular microscopic lens.
Petrographic Microscope: This type of microscopic lense features a polarizing filter, a rotating phase, and plaster plate. Petrographic Microscopes focus on the research study of inorganic substances whose homes tend to alter through shifting point of view.
Pocket Microscope: This sort of microscopic lense includes a single shaft with an eye piece at one end and an adjustable objective lens at the other. This old-style microscopic lense has a case for easy carry.
Electron Microscopes: This sort of microscopic lense utilizes electron waves running parallel to a magnetic field supplying higher resolution. Two Electron Microscopes are get more info the Scanning Electron Microscope and the Transmission Electron Microscope.
Scanning Probe Microscope: This sort of microscopic lense steps interaction in between a physical probe and a sample to form a micrograph. Just surface area information can be collected and analyzed from the sample. Types of Scanning Probe Microscopes consist of the Atomic Force Microscope, the Scanning Tunneling Microscope, the Electric Force Microscope, and the Magnetic Force Microscope.
Science wouldn't be what it is today without the microscope, as this device is the primary instrument by which the world and all of its components get more info are determined and assessed. It is with the microscope that we take a look within ourselves so we can understand and find out who we are and how we work.


I first covered the new Trijicon AccuPower 1-8x28mm in part of my 2017 SHOT Show Optics report. After SHOT 2017, I got a hold of a copy and I have been using it since then. So far I have been impressed by it. I like the bigger 28mm objective size and Trijicon’s segmented-circle first focal-plane reticle with daylight visible illumination. It’s relative short, optically it’s a great performer and it’s has a good price point for a top-tier 1-8x carbine optic.
I remember not too many years ago, when Leupold released their Mark 8 1.1-8×24 with a price tag of $8000. Although, Leupold did adjusted the price on their updated version recently but it’s still costs $2800-$3000 and up depends on the reticle option. The new Trijicon AccuPower 1-8×28 has a MSRP of $1699 but it’s now available from many place for as low as $1275. So, yes, the new Trijicon AccuPower 1-8x costs half that of the Leupold Mk 8’s price. For the purpose of this review, I will be comparing the Trijicon, made in Japan, to the U.S. made Leupold.
The Trijicon AccuPower 1-8×28’s windage and elevation turrets have build-in locking feature. Just pull it up or out to side and that will unlock the turret. The adjustment on my MOA reticle sample is in 1/4 MOA per click and on the MIL reticle model is in 0.1 MIL per click. The illumination control turret features the “off” position between each levels. I personally would just prefer low-profile capped adjustment turrets on a tactical scope.
At 1x the Trijicon offers a wider FOV than the Leupold Mk 8 by over 17 feet at 100 yards. According to Trijicon’s spec sheet, the AccuPower is a true 1x at the low magnification. Whereas, the Leupold Mk 8 is 1.1x. To be honest, I can’t tell the difference between the two. True 1x on a magnified scope is always subjective to one’s vision.
At the medium 4x magnification. Trijicon offers both red and green color illumination version of the scope. I found the green color illumination on the previous Trijicon AccuPower model is not bright enough for under a sunny day with a desert background. On my newer red color illumination AccuPower model, that’s not a problem with level 9 and above on the illumination setting. The green color illumination does have one advantage over the red color – green it is better for those with any degree of colorblindness, which affects a small but noticeable percentage of the male population.
At the max magnification of 8x the Leupold Mk 8 has a slight bigger FOV of 14.7 ft @100 yds vs the Trijicon’s 13.1 ft @ 100 yds. Probably due to its larger 28mm objective size, the Trijicon is brighter and has a much more comfortable eyebox than the Leupold Mk 8 at the top magnification levels. The Trijcon also has a constant eye-relief, while the Leupold Mk 8 has almost half inch of eye-relief change through out the zoom ranges.
The one aspect that I don’t like about the Trijicon segmented-circle reticle is its thick 4-MOA center crosshair. The MIL version’s center crosshair is slightly smaller at 1-MIL (equals to 3.4377 MOA). That compares to the 1/2 MOA center-dot found in most of the Leupold Mk 8 reticle options.
I initially mounted the Trijicon 1-8x28mm scope on a set of new Warne MSR 34mm QD rings on my testing WPA T91 piston upper. While I really like Warne rings, the configuration doesn’t offers enough front offset for the Trijicon 1-8×28 on a short AR-15 style flat-top receiver. I eventually replaced that with a Geissele Super Precision Mount. The standard M4 version of the Geissele mount is a perfect fit for the Trijicon 1-8×28.
Size wise, the Trijicon AccuPower 1-8×28 is almost an inch shorter than the Leupold Mk 8. Both are in the 34mm tube size, the Trijicon weights 1.8 ounces more and the Leupold Mk 8 has 150 MOA of turret adjustments compare to the 100 MOA of the Trijicon’s. The Leupold Mk 8 is probably a better precision scope due to its reticle choices and bigger adjustment range. The Trijicon is a better carbine optic with its shorter length, more useable daylight visible illumination, and a faster reticle for close-up. Price wise, the Trijicon AccuPower 1-8×28 is a better deal at half the cost.
Trijicon AccuPower 1-8x28mm Specification:
|FOV:||109.2-13.1 ft @100yds|
|Eye relief:||4 inch|
|Turret Adjustment:||1/4 MOA|
|Adjustment range:||100 MOA|

2 Aspects You Do Not Know In Respect To LASIK Eye Medical ProcedureThe eye can be examined with relative ease regarding both its function and its structure. A practical assessment includes the ability to relocate the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be evaluated in several methods. The client might be asked to recognize illuminated letter or objects of differing sizes on exactly what is known as the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in numerous methods. Stress within the eyeball is measured by a "tonometer." In particular diseases, particularly in glaucoma, the stress in the eyeball is increased noticeably.
It ought to be well kept in mind that a patient with an eye problem may have other issues. Frequently other physical conditions are main and affect the eye as a consequence. The appearance of the eye can inform the client and the physician to troubles in some disturbances of other parts of the body even before other signs provide themselves.
Subsequently, one's dependence on sight is highlighted when one deals with a possible or short-lived permanent loss of this crucial sense. For this reason, when corrective steps are looked for, particular forms of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are bothered with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another kind of vision here correction. The only difference is that with this type of surgery, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done utilizing an "excimer laser."
The primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea utilizing a blade known as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, permitting much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that individuals need to understand. Probably, the main reason that this type of eye surgical treatment has actually ended up being well accepted is due to the fact that many of its cases had actually achieved success.
However, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Since LASIK eye surgical treatment includes the this website operation of the retina, which is among the most sensitive portions of the eye, a lot of people say that the operation can be very dangerous.
To puts it simply, a simple error might practically trigger an individual's life time loss of sight. For this reason, it is crucial to think about many elements before choosing whether LASIK eye surgery is the best restorative measure one needs to go through.
2. It is not a best procedure
LASIK eye surgical treatment might remedy your vision but it does not necessarily indicate that it can give you a perfect vision. Even if analytical reports show that 70% of the patients may have 20/20 vision, this does not always imply they have perfect vision too.
Offered all these things, it can be deduced click this link that, in spite of the appeal of the operation, LASIK may not constantly be the perfect eye surgical treatment the method most individuals see it
Alternatively, the examination of the structural part of the eye might be made in a number of methods. It needs to be well remembered that a patient with an eye issue may have other problems. Frequently other physical conditions are main and affect the eye as a effect. The look of the eye can inform the client and the doctor to troubles in some disturbances of other parts of the body even before other symptoms present themselves.
Like its tangible counterpart, LASIK eye surgery is another kind of vision correction.

This light-field-based approach to near-eye display allows for dramatically thinner and lighter head-mounted displays capable of depicting accurate accommodation, convergence, and binocular-disparity depth cues. The near-eye light-field displays depict sharp images from out-of-focus display elements by synthesizing light fields that correspond to virtual scenes located within the viewer's natural accommodation range. While sharing similarities with existing integral imaging displays and microlens-based light-field cameras, the displays optimize performance in the context of near-eye viewing. Near-eye light-field displays support continuous accommodation of the eye throughout a finite depth of field; as a result, binocular configurations provide a means to address the accommodation-convergence conflict that occurs with existing stereoscopic displays. This demonstration features a binocular prototype and a GPU-accelerated stereoscopic light field renderer.


Shadow map is now widely used in realtime shadow rendering. The basic concept of shadow map is very intuitive. We treat the light as a camera. Watch from the light and all the invisible areas are shadows.
With this basic concept, shadow rendering always involves two passes. In the first pass, we align the camera with the light, and then render the whole scene with depth information. This is the shadow map. During lighting, we convert the pixel position to the light(shadow camera) space, then we compare the depth value the with corresponding pixel in the shadow map we rendered before. If the current pixel is further from the light, then it’s in the shadow. Otherwise it’s lit. Easy to understand and easy to implement.
Directional light’s shadow
When we build the shadow camera, we need different parameters for different types of lights. Directional light like the sunlight is considered infinite far from us. So it’s treated as a light that emits parallel light rays. So the shadow camera for directional lights is an orthogonal camera. It only has a size that can encapsulate the lights range or view camera frustum if the light is considered infinite.
Punctual light’s shadow
The most commonly used punctual light model is spot light and point light. A spot light is a cone shape light. It has an angel parameter to describe how wide it the light shape. So a square ratio perspective camera is used to render spot light shadow map. The FOV of the camera is corresponding to the angel of the light.
But a point light is a sphere shape. It’s impossible to represent a sphere with a single camera. So the most commonly used way is represent the sphere as a cube map and use six 90 degree camera to render each face of the cube map. Then during rendering, we decide which face is current pixel in, compare the depth and decide the attenuation.
Cascade shadow map
When we use a perspective camera, the pixel density of a unit world space area is not identical. Because of perspective projection, near fields of camera produce more pixels. If we use one shadow map for the whole camera frustum, it will result in either oversampling at near areas or undersampling at further areas. And because camera has a frustum shape, a lot of areas in the square shaped shadow map will be wasted.
So we split the camera frustum into several parts from near to far. Then, we use bounding volume for each part of them to render shadow map instead of using a bounding volume for the whole camera. With this approach, we have a tighter bound volume and more appropriate sampling rate for each part.
How should we split the frustum? The Parallel-Split Shadow Maps on Programmable GPUs shows us that we can lerp uniform splitting and exponential splitting based on how our camera is positioned. For example, a top-down camera can use uniform splitting, and a look-at-horizon camera which can see super far should use split more close to the exponential distribution.
Cascade shadow map is not perfect. It still has several problems:
- Though fewer areas are wasted comparing to a single shadow map, there are some repeated draws in the overlapping area between neighbor cascades;
- Cascade size varies a lot, especially when using exponential splitting. With the same shadow map size, there may be obvious shadow quality switch at the edge between cascades.
The first issue is unavoidable because we need to confirm that the shadow camera covers the cascade frustum completely to avoid unshadowed seam between cascades.
For the second problem, the common way is to do a blend at the edge of two cascades. It solves the edge problem with a cost of evaluating shadow twice at the blending area. This is a quality-performance trade off.
Stable cascade shadow map
Another problem with directional lights’ shadows is that the shadow camera always moves with our camera. And for performance reasons, under most circumstances, our shadow map is under sampled. When we rotate our camera around, light space AABB box size that corresponds to the ortho camera size changes in world space. With the shadow map size remains the same, the shadow map sampling density changes. On the other hand, when we translate the camera, a world space point’s rasterization state changes discretely in shadow map space. So when we move continuously in world space, the shadow appears to be flickering or shimmering.
For the first problem, we change the size of the ortho shadow camera from a light space AABB box to a bounding sphere. When using a sphere, the shadow camera size remains constantly when we rotating our camera like the image below.
For the second problem, we along the camera range in pixel size level with the actual shadow map. After we calculate new shadow camera position and size after the main camera moves, we re-adjust the camera position and size according to the shadow map pixel size and resolution. This will make the camera move by the integer times of pixel size and ensure that the same point in world space always refers to the same depth value in shadow map.
By comparing shading pixel light depth and the corresponding shadow map depth, we can know that if the current pixel is in shadow. This is the basic concept of the shadow map. With one sample in shadow map for each pixel, the shadow value is either 0 or 1. This will result in a very sharp shadow. Especially when the shadow map is under-sampled, the shadow will not only sharp but also aliased. So soft shadow is needed.
The most traditional shadow map is Percentage Closer Filtering (PCF). The basic idea of PCF is like all the blur methods. We sample the shadow around the light space position, and do the convolution of all the shadow results with a kernel. This will results in a blurry shadow attenuation at the edge of the shadow area. The larger the kernel, the softer the show.
Another real-world shadow feature is that the further the shadow caster to the shadow receiver, the softer the shadow. So here comes the PCSS which use a kernel size according to the shadow distance between caster and receiver. The further the distance, the larger the kernel size. This is pretty expensive, but the result is very pleasing.

An assortment of types are accessible, yet the general capacity is the same for each. The most widely recognized kind of lens hood, it is frequently utilized with standard and zooming lenses. Utilized for the most part with wide-point lenses, the exceptional petal shape keeps it from barging in the photo and cutting off piece of the picture.
In photography, a lens hood or lens shade is a gadget utilized toward the front of a lens to obstruct the Sun or other light source(s) to counteract glare and lens flare.Lens hoods may likewise be utilized to shield the lens from scratches and the components without putting on a lens cover.
The geometry of a lens hood is subject to three things: the central length of the lens, the measure of the front lens component and the measurements of the picture sensor or film in the camera.
Types of lens hood
The state of a lens hood can fluctuate from a plain barrel shaped or funnel shaped segment (much like a light shade) to a more mind boggling shape, now and then called a petal, tulip, or bloom hood. These more perplexing shapes consider the last picture’s shape and angle ratio.This permits the lens hood to square stray light with the more extended bits of the lens hood, while permitting all the more light into the sides of the picture through the shorter segments of the hood, consequently decreasing the measure of mechanical vignetting (decrease of light around the periphery) in the last picture.
The geometry of a lens hood is reliant on three things:
- central length of the lens,
- size of the front lens component,
- measurements of the picture sensor or film in the camera.
Preferably, lens hoods should increment long, and accordingly in proficiency, as the central length of the lens increments and the point of view decreases. Lens hoods are more noticeable in long center lenses since they have a littler survey point than that of wide-edge lenses. For wide point lenses, the length of the hood (far from the finish of the lens) can’t be as long as those for zooming lenses, as a more drawn out hood would enter the more extensive field of perspective of the lens.
Most extreme opening likewise influences the state of a lens hood. As the opening gets bigger the measure of light and importantly the measure of the casing the sensor “sees” increments. This can be seen when looking at two lens hoods of the same central length however with varying openings – analyze the lens hood of a fax f/4 lens with that of a similar lens yet with a most extreme gap of f/2.8.
Effectively made rectangular or square lens hoods are by and large more productive than round and hollow or conelike ones on the grounds that those shapes intently take after the state of the photo. In any case, rectangular or square lens hoods ought not be utilized with zoom lenses whose front components pivot as the central length is changed, as the hood will turn too, blocking parts of the edge of view. The same likewise applies to petal lens hoods. For these types of lenses, just tube shaped or cone shaped lens hoods will work successfully.
What Does a Lens Hood Do?
1. Lens Hoods Block Unwanted Light
2. Lens Hoods Protect Your Lens From Accidental Damage
Instructions to Use a Lens Hood
Lens hoods append specifically to the front of your lens and work best on typical, fax, and zoom lenses.
Be that as it may, I would not prescribe utilizing a lens hood with a wide edge lens. In the event that you do put a lens hood on a wide point lens, you risk the lens hood really showing up in your picture, making an overwhelming (and strong dark!) vignette. This isn’t something most picture takers need in their picture.

Eye Surgical procedure has become a mainstream approach of vision adjustment, and also this post will certainly discuss the advantages as well as negative aspects of 3 different methods being offered to the medical consumer.
Lasik Eye Surgery
LASIK is the acronym for Laser-Assisted In Situ Keratomileusis and also is an eye surgical system which permanently deals with vision by getting rid of a slim layer of the cornea. This treatment functions best on people with moderate to high levels of nearsightedness (nearsightedness), reduced to moderate levels of hyperopia (farsightedness) and also astigmatism related to nearsightedness, and that have thick corneas. It is the most widely known surgical vision correction approach.
Individuals with typical eye sight see objects plainly due to the fact that images are brought right into an appropriate focal point by the cornea as well as lens of the eye. Preferably, the cornea's curvature is equally matched to its length in a normal eye. Individuals with astigmatism, myopia or hyperopia have actually irregularly shaped corneas, so the things seen are not concentrated appropriately. LASIK adjustments corneal form by precise elimination of corneal cells, as well as by doing so corrects the eyes' focusing power.
There are, nonetheless, threats to LASIK eye surgical procedure.
There is a remote possibility of complete loss of vision. If this takes place, it is typically due to the fact that the client had a pre-existing problem which ought to have averted the surgical treatment in the first place, such as pregnancy, cataracts, joint inflammation, diabetic issues, glaucoma, or lupus. People with big students are additionally inadequate prospects for LASIK. Dry eye syndrome will certainly be intensified by this procedure.
A few individuals complain that they permanently see "ghost" pictures, have actually obscured vision, diminished contrast and also poor evening vision. When LASIK wased initially introduced, 5% of individuals had post-operative issues; however, refinements in the treatment have actually triggered this price to go down to much less compared to 1% if LASIK is executed by experienced professionals as well as patients are appropriately screened prior to surgical procedure. If problems do take place, they could frequently be resoved by a retreatment.
FDA has actually authorized LASIK laser eye surgery because 1998. While there are a great deal of pleased people, there are nonetheless no long-term researches regarding its results. Recognize the limitations and the threats of LASIK eye surgery before you sigh up for the treatment.
Though much less well known, these little implants could boost vision in clients with mild to moderate nearsightedness without the danger of permanent eye damages intrinsic in the tissue removal method of LASIK. Intacs are semi-circular disks dental implanted in the cornea which extend it to presume a flatter form. Though a little less specific than LASIK, they are removeable and also exchangeable, so if the client has an unanticipated over- or under-correction, the implant could be eliminated and one more of a various size inserted to get the desired adjustment. The implants lie at the edge of the cornea, so the central visual location is completely intact and intact, as well as the strength of the cornea is undiminished, making it a far better option for pilots and also those who take part in contact sports where eye injury is an opportunity.
Intacs are unsuitable for extreme nearsightedness and more than minor astigmatism (1.00 diopters), as the cornea can only be stretched until now. If the Intacs are eliminated, vision returns to its preoperative degree. Besides vision adjustment, Intacs are likewise used to deal with keratoconus.
Intacs are FDA approved as well as Ten Years researches have disclosed no major troubles with Intacs and also few client problems; however, because the procedure takes more training than LASIK, there are fewer eye surgical treatment centers using it. Nonetheless, the Intacs internet site offers a list of practitioners in each state, also a couple of in Canada, Europe and Mexico.
Since many people do not want to take the chance of LASIK as well as Intacs could not aid those with severe vision problems, intraocular lens implants (IOL) are a brand-new choice authorized by the FDA in 2004 to fix modest to severe nearsightedness. The Craftsmen lens, made by Ophtec, is similar to the sort of lens implant used to bring back vision adhering to cataract eye surgical procedure.
The read here brand-new IOL, called the Artisan, is planned for only patients who have 2.5 diopters or less of astigmatism.
The synthetic lens does not change the natural lens, but is placed in front of it. The main issue found with the dental implant was the steady loss of endothelial cells in the corneas of patients that received the implants. The endothelium is a layer of cells that line the undersurface of the cornea and are necessary in maintaining the cornea clear. A three-year study revealed a constant stable loss image source of endothelial cells of 1.8 percent a year. At this moment, no one could anticipate whether this loss will certainly proceed at the exact same rate forever, or even its impact on corneal function.
To minimize long-lasting impacts of the gadget on the corneal endothelium, the FDA is requiring that the new lenses be classified to define that they need to only be implanted in clients whose corneal endothelial cells are thick sufficient to hold up against small cell loss.
Much more significant issues were couple of: retinal detachment (0.6%), cataract advancement (0.6%), and corneal swelling (0.4%). The FDA is needing Ophtec to perform a five-year follow-up study of its dental implant people to much better examine the post-surgical occurrence of cataract advancement, retinal detachment as well as other sensory diseases.
The Artisan lens is intended to be a permanent implant.Though it can be eliminated surgically, vision may not always return to just what it was before getting the lens. Due to the fact that it does not influence astigmatism, people with this issue may still need glasses.

Xinglong Observatory, Xinglong County, Hebei Province, PRC.
Prof. Boonrucksar Soonthornthum, NARIT Executive Director led NARIT team to visit Xinglong Observatory as part of their visit to the National Astronomical Observatories of China (NAOC). Prof. Xiaojun Jiang, Director of Xinglong Observatory displayed his enthusiasm in showing NARIT its infrastructures and facilities NAOC has to offer on site.
Xinglong Observatory is one of the primary observatories administered by NAOC. As the largest observatory in the continent of Asia, it contains nine telescopes whose effective apertures are larger than 50 cm. The largest of them all is the 2.16-m telescope which is the first 2-metre class astronomical telescope designed and built by astronomers and engineers in China. Its main instruments include a high resolution fibre-fed spectrograph, the Beijing Faint Object Spectroscopy and Camera (BFOSC) and the OMR Cassegrain focus Spectrograph.
Xinglong Observatory also houses the Large Sky Area Multi-Object Fibre Spectroscopic Telescope or LAMOST. It is a special active reflecting Schmidt telescope which adopts an innovative active optics technique that changes the mirror surface continuously to achieve a series of different reflecting Schmidt systems at different times. It breaks through the bottleneck that has hampered large-scale spectroscopic survey observations in the past by combining a large aperture (a clear aperture up to 4.9 metres in diameter) with a wide field of view (5 degrees). LAMOST possesses 16 spectrographs with 32 CCD cameras, making it the telescope with the highest spectral acquisition rate in the world.
The NARIT Executive Director also displayed an interest in joint research work with Xinglong Observatory and LAMOST project as the facilities are prime for Thai researchers in the long run. A talk for promoting Thai students to participate in Universities of Chinese Academy of Sciences or UCAS was also mentioned as, currently, the number of Thai students under UCAS in astronomy is still relatively small compared to other disciplines.
Stay tuned for more news on the expedition of NARIT to NAOC from March 8-12, 2017

Real-time tracking of membrane proteins is essential to gain an in-depth understanding of their dynamics on the cell surface. However, conventional fluorescence imaging with molecular probes like organic dyes and fluorescent proteins often suffers from photobleaching of the fluorophores, thus hindering their use for continuous long-term observations. With the availability of fluorescent nanodiamonds (FNDs), which have superb biocompatibility and excellent photostability, it is now possible to conduct the imaging in both short and long terms with high temporal and spatial resolution. To realize the concept, we have developed a facile method (e.g., one-pot preparation) to produce alkyne-functionalized hyperbranched-polyglycerol-coated FNDs for bioorthogonal labeling of azide-modified membrane proteins and azide-modified antibodies of membrane proteins. The high specificity of this labeling method has allowed us to continuously monitor the movements of the proteins of interest (such as integrin α5) on/in living cells over 2 h. The results open a new horizon for live cell imaging with functional nanoparticles and fluorescence microscopy.


Fiber Optic Connectors are special connector for the connection of optical fibers or Fiber optic cables. Prefabricated connectors connects other such components. The corresponding prefabricated optical waveguides are called Fiber Optic Connectors which helps to connect with each other or with other such components. In telecommunications these are used in sender, receiver or amplifier and the in measurement technology these are used in spectroscopy or in medical technologies they are used in laser devices, sensors or detectors. Previously we wrote about Types of Connectors and Gender of Connectors. Also, Fibre Channel Technology and How Optical Fiber Works has been discussed.
