M. Kalpana Devi, Ch. Srinivas, T. Venkat Reddy

Abstract: In this paper, we studied energy parameters of the Point Spread Function (PSF) namely, encircled energy, relative encircled energy, excluded energy and displaced energy of an optical system apodized with Gaussian filter against the specific radius in the focal plane of imaging system. These parameters are important in the performance analysis of optical system in presence of apodisation
