Abstract
The article presents optical receivers developed on the basis of two-beam laser interferometer for registration of ultrasonic signals of bulk and surface waves in solid media in the range of frequencies up to 1000 MHz. It is shown, that laser interferometer is an "absolute" receiver, i.e. not demanding calibration for measurement of displacement inan acoustic wave. The rational design of the interferometric head is described. Block diagrams of measurements are given. Characteristics of optical receivers are shown. Specific applications of optical receiveers in various installations are described. Experience of application of semi-conductor lasers in the optical receiver is outlined.
