摘要
光纤水听器是国防技术重点开发项目之一,涉及光学、光电子学、精密机械、信号处理技术等多个领域,各发达国家都高度重视此方面的研究。文章详细讨论了Mach-Zehnder双光束光纤干涉仪基本原理、相位载波(PGC)零差检测方案,进行模型的数学分析及Matlab仿真来实现PGC解调。
Optical-Fiber hydrophone is one of the key development projects of national defense technology,and it is related to optics,optoelectronics,precision machinery,signal processing technology and other fields.All developed countries have attached great importance to this research.This article discusses the basic principle of the Mach-Zehnder double-beam optical-fiber interferometer in detail,the detection program of phase generation carrier（PGC） homodyne,the model of mathematical analysis and Matlab simulation to achieve the PGC demodulation.
