Paper Abstract

Fourier analysis can be applied to an anisoplanatic optical system, if we define the modulation transfer function of such a system as the four-dimensional Fourier transform of its space-variant point spread function. We show that this approach can be used to estimate the band-width of the output image, and thereby provides a way of determin-ing the sampling rates required for computer simulation of such systems. We also show that the computer calculation of the image is less time-consuming to do in the spatial domain than in the frequency domain.
