The Modification Scheme for a Hybrid Mach-Zehnder & Sagnac Interferomtric Fiber Optical Leak Detection System

The reason of the essay research find position of leakage point, and design a fiber optical leakage detection system. The research of fiber optical detection system in past year, because property of structure produce SNR smaller, quality of detection system is too bed. The essay brings to a hybrid Mach-Zehnder & Sagnac interferomtric can improve the SNR to 10dB. Therefore, it provides the better SNR. The experiment is added to signal process, such as PTL, PGC structure. To provide the systematic characteristic, such as dynamic range(60dB), percentage error(0.025%).
The focal of the essay provide leak detection systematic characteristics how we make use of signal process.
