摘要：
A new experiment system of three-dimensional shape measurement is presented. The advantages and the disadvantages are analyzed. In this experiment system, using digital light projector replaces traditional projector, and electronical grating replaces traditional grating. Obviously, the system has many advantages such as higher precise, easier to realize, etc. But there still are some disadvantages because of the characteristic of the system. We designed experiments to discuss the errors introduced by the system and look for the best system parameter. From the last result, we can conclude that the system has high practical value.
