摘要

本文介绍了光纤干涉水听器的结构分析。用数学方法比较了Sagnac型干涉仪的特性及灵敏度、延迟光纤和物理频率之间的关系。在实验中，我们采用PGC调制技术，测量了本文提出的三种干涉仪的灵敏度。声学信号灵敏度的初步结果如下:迈克尔逊、补偿式马赫-曾德尔干涉仪。Mach-Zehnder干涉仪和Sagnac干涉仪的混合噪声分别为-201.67、-205.97、-212.47 dB / V/1 /spl mu/Pa。

The configuration analysis of fiber optic interferometer of hydrophones

This paper describes a configuration analysis of optical fiber interferometric hydrophones. We use mathematical methods to compare their characteristics and relation of sensitivity, delay fiber and physical frequency of the Sagnac type interferometer. In the experiment, we use PGC modulation technology and measure the sensitivity of the three types interferometer in this paper proposed. The preliminary results of the acoustic signal sensitivity are as follows: Michelson, compensating type Mach-Zehnder interferometer. Hybrid of a Mach-Zehnder and a Sagnac type interferometer are -201.67, -205.97, -212.47 dB re V/1 /spl mu/Pa, respectively.
