Abstract

In phase-shifting digital holographic microscopy (PS-DHM), the reconstructed phase map is obtained after processing several holograms of the same scene with a phase shift between them. Most reconstruction algorithms in PS-DHM require an accurate and known phase shift between the holograms, requirement that limits the PS-DHM applicability. This work presents an iterative-blind phase shift extraction method based on the demodulation of the different components of the holograms using three-frame holograms with arbitrary and unequal phase-shifts. Both simulated and experimental results demonstrate the goodness and feasibility of the proposed technique.
