| Abstract: | A digital image restoration algobrithm is discussed which can eliminate the influence of non-uniform intensity distribution of diffraction halo and enhance the accuracy for computer to analyze speckle photography fringe pattern automatically. The comptlting program is also presented briefly. Test results using the algobrithm and the program to deal with analogous white light speckle photography fringe whthout noise are very satisfactory. |
