Robust phase aberration compensation in digital holographic microscopy by self-extension of holograms.

We propose a numerical robust phase aberration compensation method in digital holographic microscopy, which is based on self-extension of holograms. We remove the fringes of the sample area in the hologram, then expand the fringe to fill the removed area of hologram by self-extension. The sample-free reference hologram is obtained which contain the total aberration of the system. The quantitative phase imaging of samples is separated from measurement phase data by the difference phase map of captured and reference hologram. Numerical simulation and experimental results demonstrate the availability of the proposed aberration compensation method in digital holographic microscopy. [ABSTRACT FROM AUTHOR]
