| Abstract: | 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. |
