We propose phase retrieval from three or more interferograms corresponding to different tilts of an object wavefront. The algorithm uses the information contained in the interferogram differences to reduce the problem to phase shifting. Three interferograms is the minimum for restoring the phase over most of the image. Four or more interferograms are needed to restore the phase over the whole image. The method works with images including open and closed fringes in any combination.
我们提出从与物体波前不同倾斜度相对应的三个或更多干涉图中进行相位恢复。该算法利用干涉图差异中包含的信息将问题简化为相移。三个干涉图是在图像大部分区域恢复相位的最小值。要在整个图像上恢复相位则需要四个或更多干涉图。该方法适用于包含任何组合的开放和闭合条纹的图像。
