Apodization Defocused Optical Imaging System with Different Apertures using Hanning Amplitude Filter

Ali H. Al-Hamadani, Ghada S. Karam, Abbas S. Al-Saedi


The Optical system performance is characterized by the modulus and the phase of the amplitude impulse response (point spread function). An optical system with a nonuniform amplitude across its pupil called an apodized system. The motivation of apodizing a system is to increase the image quality of the system. In this paper, the influence of Hanning amplitude filters on the intensity of incoherent optical systems has been analyzed. A general expression for the PSF in the case of different square size pupil apertures (half diagonal=.........
