| Abstract: | Based on laser interference,digital image processing technology and the FFT method, the technic in automatic interference fringe processing for measurement of length of surface standard by interferometry is analyzed and solved. Through the method, automatization for testing process has been realized,but testing accuracy upgraded greatly. Moreover testing result of interference fringe’s fractions for measurement of length of surface standard gauge block was given as an example. |
