Abstract :
The system for an acousto-optic processor for phase and phase difference measurements (AOPP) of high frequency signals is considered in the paper. Interaction between the laser beam and acoustic waves results in the appearance of an interference pattern in the focal plane of an analysing lens. All parts of the AOPP system are discussed in detail. The analysis of the influence of disturbing factors on the interference pattern is also discussed
