Abstract

Abstract A novel procedure for shaping the lateral and axial component of the point spread function of the optical imaging system. It is possible to develop an apodized point spread function of an optical system with Hanning, Gaussian and Co-sinusoidal amplitude filters and phase filters [2], Complex pupil filters are introduced to improve the resolving power of an optical imaging system of three zone aperture [3]. Three zone aperture shading with amplitude and phase with all possible combinations in each zone have been tested for better results The optical system achieves super-resolver state with Hanning amplitude complex pupil function in the last zone of defocusing with (-π/4) and (π/3) phase filter condition. The lateral resolution of the central maxima is enhanced and the suppression of side lobes by the highest level of amplitude and phase apodization.
