It is found that the changes resulted from the inclination of the moving mirror consists of three parts: the stationary OPD due to the optical beam deflection,the offset OPD due to the different ray in the direction perpendicular to the optical axis,and the offset from the center of the deflected beam to the optical axis.

结果表明，光束偏转带来的误差分为三部分：光束偏转导致整体增加的恒定光程差，垂直光轴方向因不同光线而引入的偏移光程差以及偏转光束中心相对于光轴的偏移量。

To suppress the noise which caused by the fuzzy character of XLPE sample, the size of the photodetector was determined based on the analysis of the light intensity distribution in the spatial frequency plane when the laser beam passing through the sample was collected by lens. A series of detectors were designed to eliminate the time response decreasing effect caused by the increasing of the detector size. The developed laser system could resolve defects of 40 um diameter in XLPE tape with the 120um diameter and 400Hz scanning laser beam. after above results was used.
