Abstract
We present a phase unwrapping approach based on multiple recording distances for digital holographic microscopy. It unwrappes the ambiguous phase image by synthesizing the extracted continuous components from a set of multiple reconstructed phase images obtained from a series of holograms by slightly shifting the specimen longitudinally with a step more than the longitudinal correlation length of the coherent noise field. The experimental results demonstrate that the proposed method provides a more accurate calculation and better counteraction of phase noise than the methods proposed in previous research.
