Error Analysis of a Fiber Optic Accelerometer Based on White Light Interference
The model of the optical priciple error, the cross sensitivy error and the error induced by temperature were built. These errors have affected the measurement precision of a fiber optic accelerometer which can be used to measure the direct current signal of acceleration. With a purpose of obtaining the exact data, the simulation and experiment were conducted. Results show that, the measurement errors of interrogation algorithm decrease with the signal-to-noise ratio increasing and the spectrum sampling interval shortening, and the measurement accury is 4.5×10-5; under the effect of one time gravitational acceleration, the cross sensitivity error is 1.8 mg; the scale factor will increase(decreas) 0.79‰ when the temperature rises (drops) 1℃.
