Extension of the Time Interval for Evaluation of Broadband Signal Delays in a Multichannel Acousto-Optic Correlator with Time Integration

摘要

The possibility for extension of the time interval, controlled by a multichannel acousto-optic correlator with time integration (AOCTI), during modulation of the optical radiation source intensity by two reference signals, shifted for the period of sound propagation along the aperture of the ultrasonic light modulator, and registration of optical signals in the AOCTI output plane by two optical receiver matrices is analyzed. Effectiveness of evaluations of the received signal delay time generated by optoelectronic systems is investigated.
