摘要
Phase unwrapping has been an important way to construct a 3-dimensional image of the object in digital holographic microscopy. However, there is still a huge challenge currently on this technique at present, as it is still difficult to perfectly retrieve high wrapping density of phase maps which include different types of noise. This is because many details of high wrapping density of phase maps are buried in noise so that it is difficult to reconstruct them in digital holography. In order to solve this problem, a novel solution called I-PUROR method is presented in this paper. In comparison to previous techniques, not only can the I-PUROR algorithm effectively overcome the noise influence, but also reconstruct phase details very well in the phase unwrapping process. The experimental evaluation is fully consistent with theoretical analysis. It proves the validity of this new method.
