Abstract

Bragg cell acoustooptic processors have been used to find the complete Fourier transforms of signals using various architectures. Two dual-Bragg cell systems which implement the multiply-convolve-multiply algorithm have been used to obtain the real and imaginary parts of the continuous Fourier transform of various signals. The results are compared with the theoretically calculated transforms, and the performance of the processor is evaluated. The possibility of obtaining a complete Fourier transform using only a single Bragg cell is considered.
