Paper Abstract

We report an approach for three-dimensional (3D) imaging with use of acousto-optic fringe projector (AOFP) and a technique of piecewise temporal phase unwrapping. The AOFP is controlled by direct digital synthesizer to generate a sequence of fringe patterns with different spatial frequencies so that encoding with variable sensitivity can be realized. Furthermore, we present a new phase unwrapping strategy for incremental phase reconstruction with the level of details. The algorithm is developed as a piecewise temporal phase unwrapping with a tolerance of deviation from the condition imposed upon conventional temporal phase unwrapping technique. Preliminary experiment results are given to support proposed approach.
