Abstract:

A computer algorithm has been discovered for unwrapping two-dimensional Phase data and producing perfect contour maps without holes or dark bands of erroneous contour lines. The method employs local, temporary unwrapping within single grid squares of rectangular sampled data and the addition of extra contour levels outside the 0 to 2 pi range to fill holes.
