| Abstract: | 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. |
