Abstract

A mathematical model of the signal formation process at the output of acousto-optic delay line (AODL) with direct detection has been proposed. This model is used to derive an equation of the AODL transient response. This equation is used to derive a formula for the pulse response characteristic that is utilized to determine the AODL voltage frequency transfer factor. The exponential notation of the frequency transfer factor is discussed. Analytical expression for the amplitude-frequency response of AODL with direct detection is obtained, and its numerical analysis is carried out. The analysis results have been experimentally tested on an appropriate mock-up. The results of experimental investigations confirmed the validity of the proposed mathematical model.
