Fiber optic Bragg gratings have been used for years to measure quasi-static phenomena. In aircraft engine applications there is a need to measure dynamic signals such as variable pressures. In order to monitor these pressures a detection system with broad dynamic range is needed. This paper describes an interferometric demodulator that was developed and optimized for this particular application. The signal to noise ratio was maximized through temporal coherence analysis. The demodulator was... Topics: OBJECT-ORIENTED PROGRAMMING, SYSTEMS ENGINEERING, NETWORK SYNTHESIS, COMPUTER COMPONENTS,...
