【Abstract】 Based on phase modulation and interference detection of two beams of Mach Zehnder optical fiber interferometer, a detecting scheme to realize phase carrier modulation using PZT phase modulator and to realize demodulation of detected signal using Bessel function and Fourier analysis is proposed. Theoretical analysis shows that the scheme can effectively suppress effect of random interference signal on the measurement accuracy.更多还原
