Abstract
Phase unwrapping by a lookup table method has been used to analyze the phase map with singular points that is derived from a multiple-spatial-carrier-frequency fringe pattern. The phase unwrapping can be performed independently on a pixel-by-pixel basis without reference to the phase values of neighboring pixels, and is relatively insensitive to errors. Experimental results are presented that demonstrate the validity of the principle.
