摘　　要：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 operation principle and construction design of an all fiberoptic accelerometer based on compliant cylinders are described. The accelerometer is fabricated by supporting a seismic mass between two compliant cylinders, which tightly wrapped with single mode optical fiber and acted as two arms of the optical fiber interferometer. The two arms are coated with Al films to enhance the reflectivity. Preliminary test results indicated that the accelerometer has better frequency response well above the resonant frequency, and the output signal is in correspondence with the input.
