A Grating Generator for 3D Scanner Using CPLD

Abstract:

In the three-dimensional scanners (3D scanners), the grating generator is a key hardware. The commercial video projector is always used to act as the electronic grating generator normally. But there are some defects existed. Such as, the size is too large to setup in the case, it is not easy to be controlled by a single chip microcomputer, etc. To solve these problems, in this paper, a new type of grating generator was designed. A complex programmable logic device (CPLD) chip is used to control a liquid crystal on silicon (LCOS) video chip directly, and it works well.
