自1976年 P.Shajenko 发表了动镜式光纤水听器的研究以来,光纤水听器的类型现已多达十几种。这些光纤水听器的转换机理可归纳为声感应相位变化或声感应强度变化。声信号作用在传感元件上产生相位变
Since 1976, P. Shajenko published a study of the movement of fiber optic hydrophone, the type of fiber optic hydrophone has now been as many as a dozen. The conversion mechanism of these fiber hydrophone can be summarized as the change of acoustic induction phase or the change of acoustic intensity. Acoustic signals act on the sensing element to produce a phase change
