Query: Demodulation of spatial carrier images : performance analysis of several
  algorithms using a single image   Optical full-field techniques have a great importance in modern experimental
mechanics. Even if they are reasonably spread among the university
laboratories, their diffusion in industrial companies remains very narrow for
several reasons, especially a lack of metrological performance assessment. A
full-field measurement can be characterized by its resolution, bias, measuring
range, and by a specific quantity, the spatial resolution. The present paper
proposes an original procedure to estimate in one single step the resolution,
bias and spatial resolution for a given operator (decoding algorithms such as
image correlation, low-pass filters, derivation tools ...). This procedure is
based on the construction of a particular multi-frequential field, and a Bode
diagram representation of the results. This analysis is applied to various
phase demodulating algorithms suited to estimate in-plane displacements
