Abstract

Segmenting of the incident wavefront at the entrance pupil of an optical system, occurs in systems with segmented windows and in certain configurations of scanning systems that include polygons as the scanning element. Segmenting of the wavefront may cause a serious degradation to the MTF of the system. In some cases, the resolution of such systems may be decreased by a factor of two. In this paper, the degradation of the MTF is calculated for coherent and incoherent light. It is shown how such cases may be simulated using the CODE- V^R software. An experimental setup was performed in order to demonstrate the incoherent case and its results are presented.
