基于统计滤波的单幅散斑条纹图的相位恢复技术

Phase Recovery from a Single Speckle Fringe Pattern Based on Statistical Filtering

基于统计信号处理技术的贝叶斯 (Bayes)估计原理 ,提出一种新的滤波方法。该方法能有效减少散斑条纹图中的噪声 ,而且仅用一幅散斑条纹图就能获得准确的条纹相位分布。通过实例说明了该方法的处理过程。

A robust filtering method based on Bayesian estimation rule and statistical signal processing technique is presented. The new method can efficiently reduce the noise of speckle fringe pattern, and rather accurately perform phase recovery from a single fringe pattern. Experiment on the test image is presented to illustrate the validity and processing of the new method.
