Abstract

In a recent published work, we developed the technique to enhance the reliability of absolute phase maps by using the fringes of three spatial frequencies. However, it is time-consuming to capture the fringe images of three spatial frequencies with single channel in time sequence. To increase the efficiency of our proposed three-frequency technology, in this paper we propose a method to capture the fringe images of three spatial frequencies with multi-color channels and 3CCD camera. The projected spatial frequencies can be selected to guarantee the correctness of recovered fringe orders and avoid the chromatic aberration effect on frequency distortion. The cross talk among color channels can be eliminated effectively and the measured object can be reconstructed with high accuracy. The effectiveness of this method is verified by experimental results.
