摘要
M-Z干涉型光纤水听器三路输出解调方案中用隔直器去除信号中平均光强的方法似乎更简便,然而结果却与原方法有较大出入.为此对此过程进行了深入的理论分析,并对分析的结论进行了仿真验证,结果表明用隔直器去除平均光强的方法存在原理上的缺陷,应根据实际情况慎重选用.
The process for eliminating the average laser intensity in the signal in the 3-output demodulation method of a Mach-Zehnder (MZ) interferometric fiber-optic hydrophone seems easier, but the result differs from the primary method. The disposal process was theoretically analyzed in detail, and the analytic conclusion was simulated and validated. The result shows that the process has theoretic limitations and should be chosen cautiously.
