Paper Abstract

It has long been recognized that there exists a formal analogy between optical Fourier transforms performed by lenses and the chirp Fourier transforms implemented with dispersive delay lines. Progress in the technology for optical signal processing and for surface-acoustic-wave dispersive delay lines has advanced many signal-processing techniques from the theoretical to the practical realm. Analogous and competitive surface-acoustic-wave and optical techniques for spectral analysis, matched filtering, and convolution in one and two dimensions are compared and their limitations are discussed.
