迭代估计法单幅条纹图的相位解调

Phase Demodulation from a Single Fringe Pattern Based on Iteration Algorithm

基于相位曲面的光滑连续性,提出一种新的自适应相位解调方法.该方法通过迭代估计,能有效从干涉条纹图获得较准确的条纹相位分布.文中通过实例说明了其处理过程.

An new phase demodulation method, based on the smoothness of the modulated phase field, is presented. The method can efficiently extract the phase information from a single fringe pattern. Experiment on the test image is presented to illustrate the validity and the processing of the new method.
