英文摘要	A distributed-feedback fiber laser hydrophone with band-pass response is presented. the design of the hydrophone aims to equalize static pressure and eliminate signal aliasing of high-frequency acoustic components. theoretical analysis is presented based on electro-acoustic theory. the experimental results agree well with the theory. the measured underwater responses show that the hydrophone has a pressure sensitivity of -170 db re : pm/mu pa over a bandwidth between 100 hz and 500 hz. a sensitivity reduction exceeding -35 db is observed at 2500 hz. the tested static pressure sensitivity of the hydrophone is -226 db. the proposed fiber laser hydrophone of this kind is expected to have important application in deep water fiber-optic sonar systems with anti-aliasing, and the understanding gained through this work can be extended to a guide of hydrophone design for required filtering bandwidth.
