Abstract

The effects of amplitude nonuniformities and phase errors on the accuracy of the optical Fourier transform are considered for the case of a simple lens. A quadratic phase model is derived, analyzed, and compared to experimental and point-by-point optical path difference data. The goal is to determine the lens specifications needed to produce an optical Fourier transform of given accuracy rather than the design of the lens itself.
