Abstract
In this paper we describe and investigate different types of acousto-optic (AO) signal processing systems that have been designed and manufactured recently. We demonstrate a real- time rf power-spectrum analyzer (RTSA) operating in the 50 - 100 MHz frequency range with high resolution of 35 kHz. Then we present a microwave power-spectrum analyzer operating in a wide frequency range from to 2 GHz with resolution of 1 MHz. The systems are members of an AO-RTSA family mounted in a 19" rack with compact size and vibration free optical part. The received rf and mw signals are digitized, transferred with high speed interface to then processed by a 486 embedded computer. The system bus and modular setup allows the extension -- or reconfiguration -- of the system with various additional units if necessary for a particular application.
