Abstract
Adequate discrete representation of optical transforms in digital computers is of the critical value for digital processing of optical signals, digital synthesis of optical elements and for computer simulation of optical systems. In the paper, from a unified point of view of signal theory, discrete representations of such optical transforms as Fourier Transform, Fresnel Transform, and convolution integral are briefly described an a base of a correspondence principle between analog and discrete transforms.
