Abstract
Compansive diffraction nonlinearities reduce the noise and improve the performance of joint transform correlators. The compression and expansion of the photorefractive two-beam coupling parallel optical device is similar to that of the limiting square-law serial electronic receiver. Computer simulations of this device indicate superior performance over a wide range of noise levels.
