摘要
光纤水听器是在传统的水听器的基础上,从一个全新的光纤技术出发,实现传统的水声传感和声纳数据传输一体化,从而改善声纳系统的可靠性,并且降低其制造、使用和维护的总成本的新型水听器。文章简要介绍了光纤水听器的工作原理和结构,包括干涉型光纤水听器、强度型光纤水听器、光纤光栅水听器等三种。详细地对它们在国内外的发展以及应用方面进行了介绍。
The fiber-optic hydrophone was developed to satisfy the urgent demands of underwater acoustics applications, especially for anti-submarine purposes .This new underwater acoustic sensor based on optical fiber and opto-electronics technology is now well developed and widely used in military and civil applications. The optical fiber hydrophone system including the weak signal sensing and transferees all fiber based, and thus has the merits of light weight, low-cost and immunity to electro-magnetic interference. The history and development of the fiber-optic hydrophone are reviewed, with detailed discussion of the principle and applications of three main hydrophones.
