FIBER OPTICS DEVICE FOR DETERMINING THE BEARING TO HYDROACOUSTIC BEACON

摘要

FIELD: underwater acoustics, surface fleets. SUBSTANCE: turns of fiber coils in the interferometer are wound according to the sine law with period. The turns of one coil are shifted relative to the turns of the other one by a half of the period. The hydroacoustic beacon directs acoustic waves with period ?| to all sides. The fiber interferometer receives these waves, turning the fiber coils in the direction of arrival of the waves with the aid of the rotating system. As a result, the desired bearing is found. EFFECT: enhanced accuracy.
