Paper Abstract

The design of wideband Acousto-Optic receivers with real-time signal processing capabilities is severely limited by the sequential readout characteristics of available monolithic photodiode arrays. An alternative receiver design, using a photo sensing concept that employs a linear fiber optic array is considered here. Each fiber in the array is connected to its own photosensor, video detector and threshold circuitry. The array cir-cuitry is interfaced with a digital processor capable of real-time analysis of the array output. The receiver, consisting of an acousto-optic spectrum analyzer, the fiber array and processor can measure signal frequency and time-of-arrival over wide band widths. This paper describes the characteristics of the fiber array and the system processor.
