Paper Abstract

This paper describes an acousto-optic interferometer that is capable of measuring the instantaneous phases of wideband radio frequency (RF) signals. A novel homodyne detection concept was proposed in the implementation of the acousto-optic phase interferometer (AOPI). The AOPI was utilized to construct a channelized instantaneous frequency measurement (IFM) receiver. A breadboard of the AOIFM was built and tested. Experimental results of the breadboard are reported in this paper.
