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.
