All Optical Shipboard Sensing System

The specific innovation is to use a single optical fiber sensor/signal processing technology to measure three parameters, (i.e., temperature, pressure, and flow) with resolution adequate for shipboard and industrial applications. The Navy needs an all-optical sensing systems in ships of the future to minimize the vulerability to electromagnetic interference. The project objectives are to: optimize the design a Fabry-Perot fiber-optic sensor for the target operating ranges, repeatability, and resolution; design unique transducers for temperature, pressure, and differential pressure to integrate with a Fabry-Perot optical fiber sensor. The proposed effort will involve: an evaluatation the technical feasibility of the sensing system design concepts; fabrication and demonstration of a single sensor/signal processor. The proposed workscope will demonstrate the technical feasibitity of fabricating robust integrated fiber-optic sensing system that can measure temperature, pressure, and flow with functional performance adequate for Navy shipboard applications.
