Paper Abstract

Two acoustooptic spectrum analyzers are described. In both system the detector array is replaced by an acoustooptic Bragg cell driven by a short RE pulse and a single fast photodetector. With the power spectrum analyzer system a time-bandwidth product (TBWP) of > boo, a speed of <5o ,us, and a dynamic range > 4o dB can be achieved. Mixing the diffracted beam with a local oscillator an interferometric system is realized where an increased dynamic range of 7o dB can be achieved with the same speed and TBWP.
