摘要：

The interferometric vibration sensor with quadrature detection can generate orthogonal signals by optical configuration. The influence of the DC component existing in the interferometric orthogonal signals is discussed in this paper. The signals were processed by time derivation and arctangent algorithm to demodulated the analog signals. Theoretical analysis and experimental results prove that this method can be used to eliminate the DC component in the signal, meanwhile, the micro-vibration signals can be measured accurately.
