Paper Abstract

Practical adaptations of existing acousto-optic processors are advanced which result in systems inherently capable of attaining accurate, high-speed linear analog numerical processing with realistic components and simple drive electronics. The systems presented are heterodyned space-integrating configurations driven by multiple diode laser sources. All signals in the systems are encoded on quadrature temporal carriers, allowing bipolar and complex-valued data to be processed. This also enables the diode lasers, acousto-optic cells, and output detectors to be used in their most inherently linear operating modes, and significantly reduces the effects of temperature and prior input data on the absolute accuracy obtained. Applications of such processors are considered.
