Paper Abstract

The Arithmetic Fourier Transform is a numbertheoretic method for calculating Fourier coefficients of continuous time signals. In this paper, we present an efficient realization of the arithmetic Fourier transform algorithm on an optical parallel processor consisting of fiber optic tapped delay lines. The performance of the algorithm in presence of optical errors and noise is analyzed. From results of numerical experiments on a simple test signal we observe that the performance of the algorithm is affected minimally by roundoff errors of the optical system.
