Abstract

A series of fiber-optic acoustic sensors based on the Sagnac interferometer are described. Features of these sensors include filtering of low-frequency signal components, use of a laser light source as an amplifier, and selection of the mechanism whereby the acoustic signature is impressed upon the light beams propagating in the fiber coil.
