文摘

A phase demodulator is proposed to overcome bad SNR in optical fiber oxygen sensors. Theory of the phase demodulator is introduced in detail. Performance of the demodulator is verified by a commercial lock-in amplifier. The phase demodulator based optical fiber oxygen sensor achieves a good effect.
