    摘要:

    文章介绍了光纤激光水听器的基本原理,国内外光纤激光水听器的研究进展以及发展趋势,同时,详细介绍了 2005 年以来中国科学院半导体研究所在光纤激光水听器技术方面的研究工作,包含了标量水听器技术、矢量水听器技术、水听器阵列技术、外场实验及行业应用等。目前,课题组光纤激光水听器声压灵敏度优于-140 dB re 1 pm/μPa,频响区间 20~2000 Hz,拖曳阵列外径小于 30 mm,阵元数目 64。我国的光纤激光水听器阵列技术正处于从实验室走向应用的重要阶段,开展好实用化研究是当务之急。

    Abstract:

    In this paper, the principle of fiber laser hydrophone was presented, and the development of fiber laser hydrophone was described. Researches on fiber laser hydrophone technology of our group were reviewed. It contains technologies on fiber laser hydrophone, fiber laser vector hydrophone, hydrophone array, field tests and application areas. The static pressure sensitivity of fiber laser hydrophone is better than-140 dB re 1 pm/μPa, from 20 Hz to 2000 Hz. The diameter of towed array is thinner than 30 mm, and the number of its elements is up to 64. Fiber laser hydrophone technology is coming into application from laboratory. We believe that the researches on practical application are of great importance.
