Paper Abstract

This paper reviews the development progress of fiber optic interferometric acoustic sensors at OPTIPHASE, INC. The primary development objective is to evolve fiber optic interferometric sensor technologies which are cost compatible in their respective application methods. This mandates that only low cost approaches be considered. The sensor technology chosen involves extrinsic Fabry Perot devices configured as low finesse sensors which are compatible with low-cost dual wavelength interferometric demodulation techniques (also developed by OPTIPHASE). This paper addresses both single element and multi-element sensor systems.
