摘　　要：介绍一种新型的单模光纤环形诸振腔构成的干涉型水听器．环形谐振腔有很高的光学细度．用它做成的水听器有极高的接收灵敏度．约-125dB（参数级IV／μPa）．This paper introduces one new type interferometuc hydrophone which is constitued by a simple mode optic fibering resonat cavity. The ring resonat cavity has high optic fineness.The hydrophone is made from above ring resonat cavity. That hydrophone has one extrem high sensitivity which is nearly about-125 dB (reference level 1 V/μPa)
