光纤传声器概述

Fiber optic microphone

对光纤传声器的研究现状进行了总结。首先分别对强度型、光纤光栅型和F-P干涉型光纤传声器展开论述,通过对产品的技术现状对比,得出各类型光纤传声器的优劣势。之后对新型光学传声器进行了介绍,指出虽然新型光学传声器具有体积小、功耗低、成本低等优势,然而其主要针对特殊应用领域。最后阐述了作者在强度型光纤传声器方面的研究成果,为光纤传声器的进一步研究奠定了基础。

The fiber optic microphone is summarized in this paper, which includes the intensity modulation, fiber Bragg grating and F-P interferometric fiber microphone. The advantages and disadvantages of each kind of optical fiber microphone are obtained by comparing the technical status of the product. Two kinds of novel optical microphone are introduced, which have the advantages of small volume, low power and low cost, but for the special application. In the end, the intensity mod- ulated fiher optic microphone are experienced, which lays a foundation for further research of the fiber optic microphone.
