介绍了顺变柱体型全光纤加速度检波器的工作原理及结构设计。该检波器包括两个顺变柱体和一个质量块 ,两顺变柱体上都紧紧地绕着单模光纤 ,形成了迈克耳孙干涉仪的两个臂。两干涉臂的端面镀有高反铝膜。初步测试结果表明 ,检波器在共振频率以上有较好的频率响应 ,输入信号与输出信号吻合得较好。
The working principle and structure design of the cocular column full fiber acceleration detector are introduced. The geophone consists of two cocular cylinders and one mass, both of which are tightly wrapped around a single-mode optical fiber to form the two arms of the Michelson interferometer. Two interference arm plated with high anti-aluminum end face. Preliminary test results show that the detector has better frequency response above the resonant frequency, and the input signal matches the output signal better.
