Abstract

In this paper, the equations and the contrast of moire fringes, the sensitivity, and the maximum distance allowed between the two gratings in moire deflectometry (MD) are studied in detail on the basis of wave optics. In the analysis the affection of the transfer function for the propagation of a wavefield and the object-image conjugation are considered.
