Acoustooptic spatial filter based on a coherent coupling line
Abstract
The paper presents an investigation of the amplitude- and phase-frequency characteristics of a spatial acoustooptic filter consisting of an He-Ne laser, an acoustooptic cell, a two-wire optical delay line, and a heterodyne photodector. An attempt is made to control the parameters of the laser generating heterodyne interferometer when it is used as a high-sensitivity sensor.
