Abstract
For real-time superlarge data arrays processing computers are required to provide the speed eiectronics fails to achive. A way for increasing of calcu-lating devices speed can be based on applying the optical methods which enable to reach information processing rate of 1012 operations per second with the theoretically predicted energy consumption limit of about 1 fJ per bits'. Good examples of analog signal processing methods are rf spectrum analysis and correlations 2. For numerical computation, however, optical analog processing cannot offer high accuracy 3, to obtain which digital calculations need to be used. In this paper we present some experimentally proved ways for improving operating characteristics in both analog and digital fields of optical proces-sing. Wave heterodyning technique causes essential increase of processing ac-curacy and central signal frequency of analog acousto-optic spectrum analyzers and correlators. The application of NRZ code in acousto-optic digital multiplayers increases twice their accuracy or reduces the necessary light aperture.
