Paper Abstract

In this paper, we measure the object profile using digital Moire based on digital spatial phase-shifting technique. Perform phase unwrapping based on improved composite mask technique. Finally, add the gray image to the real coordinate 3D map of the object, we can acquire a 3D texture image of the object - the quasi-hologram of object. Theoretical analysis and experiment results are given to demonstrate the technique.
