Based on the Moire effect in shadow-casting of two coded masks a new kind of optical method is proposed to map phase variation on the object image with an extended incoherent illumination.
基于莫尔效应，本文提出了一种利用白光面光源进行双编码栅反向投影，以等位线条纹的形式测量物体相位变化的新方法。
First, 3d data field was pretreated to a unitary and integral field, and the method of 2d image segmentation was extended and amended, which makes the method be used to segment 3d data field.
