Time Integrating Acousto-optic Receiver with Wide Bandwidth and High Sensitivity

摘要

As an important method of signal receiving and processing, acousto-optic receiver can intercept wideband signal in RF domain. A large number of narrow channels for measuring RF signal can be realized by acousto-optic Bragg diffraction. The weak signal detection with high sensitivity can be implemented using time integrating photodetector array. In this paper, the principle and characteristics of time integrating acousto-optic receiver are investigated. The acousto-optic receiver with 1GHz bandwidth is demonstrated in experiment.
