ABSTRACT:
This invention is an optimized planar fiber optic sensor utilizing robust design having high acoustic sensitivity and reduced acceleration response over that found in the prior art. A continuous optical fiber sensing arm is wrapped around a plurality of mandrels to reduce acceleration effects. An optical fiber sensing arm is embedded in an epoxy material to effectively eliminate the effects of the acoustic medium on the reference arm. The sensing arm and reference arm, along with input and output couplers, are encapsulated within an elastomer, natural rubber or butyl rubber which is an active element that providing high acoustic sensitivity. The mandrels may be solid compliant mandrels, tubular cylindrical mandrels and combinations thereof.
