Abstract:
A formula of Minimum L2-norm two dimensional phase unwrapping are derived based on relationship between wrapping and unwrapping phase in this paper. In order to test the correctness and validness of the formula derived, the com- puted results of Minimum L2-norm two dimensional phase unwrapping are compared with that by traditional Goldstain’ s method. The results manifest that Minimum L2-norm two dimensional phase unwrapping can get the better results only at the sixth step iterated than that by Goldstain’ s method.
