Abstract

This paper reports the demonstration of a coherent frequency channelization and down conversion system for RF spectrum analysis. In this system, RF local oscillator signals modulate an optical beam which is then demultiplexed by a wedged etalon. Each of the resulting spatially separated channels are mixed with an incoming RF signal by heterodyne detection which down converts and channelizes the signals for further AO spectrum analysis. The performance of a concept demonstration system is discussed.
