Distributed Bragg Reflection

In this paper, the basic theories and characteristics of distributed Bragg reflection (DBR) fiber laser and distributed feedback (DFB) fiber laser as hydrophone were described and analyzed; The interferometric demodulation technique of the underwater acoustic signals from fiber Bragg grating (FBG) hydrophone was discussed; And the theoretical experimental conclusions of the ultra-thin fiber Bragg grating hydrophone were introduced; Finally, the application in the torpedo homing field of the research on the ultra-thin fiber Bragg grating hydrophone were prospected.
