OPTICAL DATA PROCESSING STUDY

Abstract

An optical data processing study was performed to determine the value of the use of present day coherent optical processing techniques on selected AFFDL data processing problems. Optical, digital and analog implementation of Power Spectral Density, Cross Spectrum, Auto and Cross Correlation, Transfer Function, and Filtering (Convolution) were considered for a wide variety of input data: from low frequency Clear Air Turbulence (cycles/hour) to high frequency acoustic data (10 KHz).
