Advanced PSF and MTF Calculation of Imaging System

For practical imaging systems, their performance can be greatly affected by the apertures. In different system setups and under different illumination conditions, the actual shape of the apertures may vary a lot. To investigate such effects, an imaging system consisting of a collimation objective and human eye is modeled. By changing the illumination conditions, the cases with fully and partially illuminated apertures are studied by checking the PSF and MTF.
