本文先简略介绍了干涉型光纤水听器的基本原理与检测信号的基本方法,由此给出了光纤水听器相位归一化灵敏度、相位灵敏度、电压灵敏度的定义。在分析它们的物理意义以及相互之间关系的基础上,给出一组能反映它们对应关系的一组数据,以及一光纤水听器探头频率响应曲线。
In this paper, the basic principle of interferometric fiber hydrophone and the basic method of signal detection are briefly introduced. The definition of phase normalized sensitivity, phase sensitivity and voltage sensitivity of the fiber hydrophone is given. Based on the analysis of their physical meaning and their relationship to each other, a set of data which can reflect their correspondence and a frequency response curve of a fiber hydrophone probe are given.
