Fiber Optic Detection of Low Frequency Underwater Sound.
Abstract
Theoretical and experimental studies of acousto-optic interferometry were continued. An experimental test of the differential loop interferometer demonstrated that the theoretical sensitivity limit can be achieved with acoustic frequencies from kHz to 50 kHz. The Michelson interferometer was studied under an environmentally stabilized configuration, but the theoretically sensitivity limit was not achieved. A Fabry-Perot configuration was analyzed, giving a theoretical prediction of very high sensitivity per unit fiber length. (Author)
