Mixed Interferometric Distributed Fiber Optic Sensor PGC Demodulation Module Design and Experimental Data Analysis
摘要
Abstract
In conventional PGC(Phase Generated Carrier)dulation using analog circuit circuit aging,positioning the phenomenon such as drift,to architecture based on the digital platform of PGC demodulation interferometric fiber optic sensor,using phase scrambler improved the PGC demodulation circuit,and testing the system function module analysis,finally the effect of the PCG demodulation circuit demodulation experiment simulation,simulation results show that the improved circuit of PGC demodulation performance good,after a phase perturbation frequency signal and the correlation coefficient of more than 96%of the signal under test,the harmonic distortion is less than 2%,at the same time phase scrambler can effectively improve the PGC demodulation output is not stable and the distortion.关键词
