Abstract

This paper discusses the methods of real-time correlation operation performed by the acousto-optic Bragg cell

and develops the mathematical models of the acousto-optic signal processing system that provides the correlation of high-speed digital pulse trains

and a description of the system performance. The system utilizes a semiconductor diode laser

a Bragg cell with bandwidths of 100 MHz and aperture times of 7.4 μs

some lens and a photodiode-detector to perform the correlation operation in real time. With Barkor code sequences and its time inverse as inputs

the experimental results that correspond with the theory are obtained.
