Development of an Interferometric Fiber-Optic Sensor and Its Array′s Divide/Combine Polarization-Induced-Fading Eliminated Technique
摘要
Abstract
A new theoretical analysis is given to the divide/combine polarization-induced-fading eliminated technique of an interferometric fiber-optic sensor and its array, and a new way is proposed to realize the real time detection of the divide/combine method by squaring each signal and adding them together. The maximum amplitude fluctuation of this method is calculated, and the conclusion is drawn that three is the best number of analysis. By adding an electronic automatic gain control circuit, the signal fading is recovered at the expense of a relevant signal/noise ration degradation, and the application of the method in the interferometric array is designed.关键词
