提出一种基于数字莫尔的三维光学数字成像系统。 此系统采用了非相干光投影和空间相移算法以及混合模板相位复原技术来重构连续位相分布图。 给出一种光学几何灵敏度的确定方法并由此获得空间自由表面的三维数字图像。 文中还给出由该光学数字化系统得到的真实人体面部的三维数字图像的实验结果。

A 3D digital imaging system based on white-light digital moire is presented. The system makes use of incoherent illumination and a spatially digital phase-shift algorithm as well as an efficient phase unwrapping algorithm with the composite-template construction technique. In addition, an approach to the determination of optical geometry sensitivity is given from which the 3D digital image of surface topography can be obtained. The 3D digital image made on a human face as an experimental result is shown.
