Fiber optic accelerometer based on clamped beam

摘要：

　　In this paper a fiber optic accelerometer (FOA) based on camped beam is proposed.The clamped beam is used as the elastic element and a mass installed on the clamped beam is used as the inertial element.The accelerometer is based on a fiber optic Michelson interferometer and has a sensing arm and a reference arm.The optical fiber of the sensing arm is wrapped on the clamped beam and the mass,which are both cylinder shaped.The sensitivity of the FOA is analyzed based on the theory of elasticity;the frequency response is analyzed based on the theory of vibration.Experiment is carried out to test the performance of the fiber optic accelerometer.The experiment results show a high sensitivity and a flat frequency response within the low frequency range of 5-250 Hz,which agrees well with the theoretical result.
