Phase Indeterminacy in Phase Analysis Methods for Spatial Carrier Fringe Pattern
The phase indeterminacy of single frequency fringe pattern and bi frequency fringe pattern in phase analysis method has been theoretically analyzed. The phase data can be determined when the ratio of two frequencies is an irrational number in spatial bi frequency fringe pattern. A simple and robust phase unwrapping by a lookup table method for this bi frequency fringe pattern is proposed. Experimental results are presented that demonstrate the validity of the method.
