Study the Image of Line Object for Optical System Using Synthetic Circular Aperture

Abstract

In this research, the line spread function)LSF( has been investigated for group of circular synthetic in place of one circular Aperture which usually used in optical systems, which use optical system diffraction limited or contain focus error (W20=0.25λ,0.5λ), when the Aperture (N=1,3,5,7).The results have been showed that the increment of number of multiple circular Aperture leads to increase the image intensity of the line object and resolution power for optical system, also the circular Aperture which contain seven multiple Apertures was a preferable from the other.
