ABSTRACT:
Apparatus for determining physical parameters of a disturbance using a fiber optic coil and linearly polarized source light. The apparatus directs a linearly polarized source light through the fiber optic coil being effected by a disturbance, and then measures the effect by comparing optically the source light and the light affected by changes in fiber coil index to detect and develop digital data related to frequency and amplitude of the disturbance.
