Acoustic antenna based on fiber laser hydrophones

Abstract: For underwater surveillance applications, an all-optical acoustic array technology allows enhanced capabilities compared to conventional piezoelectric antenna in terms of compactness, robustness and large distance remote interrogation through small diameter optical cable. One major issue about this kind of antenna is the design of a compact sensitive optical hydrophone which is optimized for reduced temperature sensitivity and high static pressure capability. This paper presents the results obtained on a first… Show more

“…It was the first time that a fiber laser hydrophone tested the sea state zero (SS0) [2]. In 2014, F. X. Launay introduced a two-dimensional array of 12 fiber laser hydrophones with a pressure sensitivity of 103.5 dB (re Hz/Pa) at 1 kHz [3]. In China, the 23rd Institute of China Electronics Technology Group, Navy Engineering University, and National University of Defense Technology have done a lot of research on the systematic fiber laser hydrophone technology [4][5][6], and this work is mainly concentrated on the hydrophone basic technology and reuse tests.…”
