Paper Abstract

A quite simple numerical model for the wave-optical simulation of the interference in a grating lateral shearing interferometer with a periodic light source and a large lateral shear is presented. Aberrations of the collimating lens will generate a spatially varying modulation in the interference pattern. The model assumes that the light source itself is completely spatially incoherent so that only the light from each point of the light source has to be propagated wave-optically through the optical system. Then, the intensity distributions of all light source points in the detector plane can just be added. The simulations are compared to theoretical calculations of partial coherence theory and also to experimental results.
