Abstract

A technique for optically processing time varying signals has been investigated. The electronic optical system described in this paper readily provides the power spectral density content of an input time function. The objective of this effort was to design a prototype coherent optical processing system to generate the power spectral density of electrical signals supplied directly from a sensor or stored on magnetic tape. The task encompassed a definition of functional components, investigation of important parameters, performance tests, and measurements.
