Computer modeling of the effects of apertures in the Fourier-transform plane of Fourier-transform imaging systems.
Two computer models are presented that can be used to determine the image formed by a 4-∱ Fourier imaging system with an aperture in the Fourier-transform plane of the system. These models were designed to aid in the selection of system parameters in a Fourier-transform hologram recording system (namely, object size, feature ratio, focal length, and storage area) required to obtain a retransformed image of a given quality. The results of the simulations are verified in the laboratory.
