Abstract

In this study, the novel rotation algorithm is proposed for the phase unwrapping algorithm. The main advantage of proposed algorithm is that it can simultaneously resolve the shifting error, holes, two types of noise (i.e. the residual noise and noise at height discontinuities). By contrast, the common phase unwrapping algorithms which operate phase shifting by 2π, can only filter two types of noise. Unfortunately, these common algorithms can not resolve the problems of the shifting error and holes. Therefore, compared to these common algorithms, the proposed rotation algorithm is more effective and useful for resolving the problems of holes and noise.
