Abstract

The image of incoherently illuminated point object (point Spread Function) will be analyzed theoretically for imaging system with different apertures. Both free and defocused systems were considered. A new formula has been derived for determination of the PSF by integration over different square size pupil apertures. Our studies show that the optimum balance for square aperture with half diagonal =1 gives a best Strehl ratio, while the resolution of square aperture with area =p have a higher resolution, and the tolerance of the different aperture solved analytically.
