Realization of Phase Generated Carrier Scheme Interferometric Fiber Optic Sensor
摘要
对干涉型光纤传感器的相位载波(ＰＧＣ)调制-解调技术进行了研究，分析得出了新的相位载波检测带宽要求，并在实验室中用相位载波检测方式检测到了较为稳定的模拟传感信号，证实了本文的理论分析。
Abstract
The phase generated carrier (PGC) modulation-demadulation scheme of the interferometric fiber-optic sensor is studied. The new bandwidth requirement of the scheme is analyzed, and stabilized analogic sensing signal is obtained by PGC detection scheme in the laboratory environment, which proves the paper's theoretical analysis.
