Title :
The interferometric frequency measurement with variable acoustooptic delay line
Abstract :
The conditions for operation of a two-beam interferometer based on an acousto-optic variable delay line are studied. The accuracy of RF signal frequency measurement is estimated, the main physical factors affecting the real measurement accuracy are analyzed. The requirements to the parameters of the acousto-optic delay line are formulated. The possibility to extract and measure the clock frequency of binary pulse trails for synchronizing a receiver in digital communication systems is shown theoretically and experimentally
