| 摘 要： | 本文根据Ｍａｃｈ－Ｚｅｈｎｄｅｒ光纤干涉仪相位调制及双光束干涉测量的特点，介绍了一种采用相位调制器（ＰＺＴ）实现相位载波调制，利用Ｂｅｓｓｅｌ函数进行傅里叶分解实现对相位调制信号解调的检测方案。理论分析表明，该方案能有效地抑止随机干扰信号对测量精度的影响。

| Abstract: | Based on phase modulation and interference detection of two beams of Mach-Zehnder Optical Fiber Interferometer, we proposed a detecting scheme to realize phase carrier modulation using PZT phase modulator and realize demodulation of detected signal using BesselFourier analysis. Theoretical analysis has proved: the scheme can effectively suppress effect that the random interference signal would give measureing accuracy. |
