Query: Achromatic Non-Interferometric Single Grating Neutron Phase Imaging   We demonstrate a simple single grating beam modulation technique, which
enables the use of a highly intense neutron beam for phase imaging and thus
spatially resolved structural correlation measurements in full analogy to
quantum interference based methods. In contrast to interferometric approaches
our method is intrinsically achromatic and provides unprecedented flexibility
in the choice of experimental parameters. Utilizing merely a macroscopic
absorption mask unparalleled length scales become accessible. The results
presented, including application to a variety of materials, establish a
paradigm shift in phase imaging.
