I found extented nijboer zernike diffraction theory and it fits to my needs. There is a lots of resources on that at google. One thing amazed me that online book writes about use of ray tracing is fits to old lenses , say latest 50s. After need use of wave theory , zernike solves the problems. Author talks about the possibility to find PSF with that method. I dont know how finding PSF contributes if you find the all phase of the system with zernike method. I know OTF and MTF derives from that method.
What else PSF,OTF,MTF contributes to if I have the phase. What they say about unsaid , if there is any ?
Anyone ?
