Paper Abstract

In this article, a novel technique of fiber sensor demodulation for fiber Michelson interferometric sensor is proposed. The output optical signal of the interferometric sensor is processed by a hybrid optical bistable device in frequency domain. When the optical path difference between the two arms of the sensor changing, it will cause the bistable device switching on and switching off. The measurement is realized by counting the optoelectronic pulses. The experimental and simulation results show that this technique with high accuracy, the resolution of the length measurement is nanometer level.
