Paper Abstract

Here a new flash phase-shifting method has been prosed. In this method, the phase difference between three consecutive Moire images is achieved by changing the illumination angles. A theoretical derivation is presented, and certain formulas are obtained to calculate 3D information of the measured object. The special phase unwrapping algorithm connected with this phase shifting method is also solved out. At last, experiment result have been given to compare with theory derivation.
