散斑摄影 条纹图 数字图像复原技术 衍射晕 speckle photography fringe pattern digital image restoration method diffraction halo
摘要
本文提出了一种消除衍射晕非均匀照度影响、提高计算机自动测量散斑摄影条纹图精度的数字图像复原算法.简单介绍了散斑摄影条纹的自动分析过程.在VAX-11/785计算机上对模拟的无噪声白光散斑条纹进行验证,结果表明,本算法和程序是可靠的.
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.
