Abstract

Baseband demodulation, lock-in detection, noise reduction, compression/expansion nonlinearities, and correlation receivers are common subjects in communication theory. In this paper we use photorefractive materials to show how real-time holography can be used to implement these temporal electronic signal processing techniques as spatio-temporal optical signal processing on images.
