实验表明，采用该方法对光纤准白光干涉信号零光程差位置的定位精度优于0.5个干涉条纹。
The experiments show that the positioning accuracy of extrapolation method for zero optical path difference point of fiber quasi-white interference signal is less than 0.5 interference fringes.

光学系统采用白光灯加准直镜，以平行光照射光栅面，通过光栅副产生莫尔条纹。
The optical system uses the fluorescent lamp with the collimation mirror, incident the grating surface by the parallel light, in order to produce the moiréfringe through the grating.
