摘要：
The noise of plasma laser interferogram is removed with binary wavelet transform. The processed results of the simulation interferogram obtained by use of simple threshold cutting method and correlation coefficient cutting method are introduced, respectively. The study shows that since the background noise characteristics of the interferogram and the noise uncorrelativity under different scale characterizations are applied, both methods can remove noise, and the later efficiency is better.
