A high-sensitivity fiber accelerometer based on multilayer fiber coils is proposed. Acceleration sensing principle of the sensor is analyzed in theory, and with the finite element software, simulation model is built. Two kinds of fiber optic accelerometers with different multilayer fiber coils are designed, and the performance tests are conducted as well. Experimental results show that the sensitivity of accelerometer based on multilayer fiber coils can reach thousands rad/g, and the equivalent transfer coefficient between different layers in multilayer fiber coils is 0.39.
