Abstract

In this paper a novel optical Fourier transform system for several wavelengths is designed. In the system two techniques are adopted; one is the use of a non-focal diffractive optical element to correct the spherical aberration and get the largest space bandwidth product; the other is the introduction of the concept of harmonic diffractive optical elements to realize Fourier transform for multicolor light. Compared to the traditional optical Fourier transform system, this pure diffractive system can acquire better performance with much simpler structure, and more prospective application in optical signal processing system.
