摘要
相位生成载波(PGC)在光纤传感器信号处理中是一种很重要的解调方法。本文首先阐述PGC实现的原理,然后重点介绍各种相位生成载波类型的解调方法,并且分析和比较了以下方法:经典的PGC解调法、Arctangent式PGC解调法、高次谐波分量PGC解调法、双路干涉信号的DCM-PGC解调法。
Phase generated cartier （PGC） is a very important demodulation method in optical fiber sensor signal processing. This paper first explained the principle of PGC implementation, focused on the demodulation methods of various phase generation carrier types, and analyzed and compares the following methods： classical PGC demodulation, Arctangent PGC demodulation, high harmonic component PGC demodulation, and DCM-PGC demodulation method for dual interference signal.
