Deep-turbulence wavefront sensing using digital holography in the on-axis phase shifting recording geometry
TL;DR: In this article, the effects of deep turbulence in long-range imaging applications presents unique challenges to properly measure and correct for aberrations incurred along the atmospheric path, and different recording geometries offer different benefits depending on the application of interest.

Matrix p- norm for phase retrieval under generalized three-step phase-shifting and its application on a red blood cell
TL;DR: Based on the matrix p-norm algorithm, a phase retrieval method applied to the generalized three-step phase-shifting interferometry (PSI) is proposed in this article, where only three phase shifted interferograms are required without any other measurements.

TL;DR: A new method is proposed in which the distribution of complex amplitude at a plane is measured by phase-shifting interferometry and then Fresnel transformed by a digital computer, which can reconstruct an arbitrary cross section of a three-dimensional object with higher image quality and a wider viewing angle than from conventional digital holography using an off-axis configuration.

TL;DR: The principle of recording holograms directly on a CCD target is described and a real image of the object is reconstructed from the digitally sampled hologram by means of numerical methods.

Digital Image Formation From Electronically Detected Holograms
Joseph W. Goodman,R. W. Lawrence +1 more
TL;DR: In high precision holographic imagery of weak objects of small angular subtense, electronic detection and digital image formation have distinct advantages as mentioned in this paper, and experiments with a vidicon detector and a PDP-6 computer have yielded reconstructed images of good quality with computation times of five minutes.

Image formation in phase-shifting digital holography and applications to microscopy
TL;DR: This work discusses image formation in phase-shifting digital holography by developing an analytical formulation based on the Fresnel-Kirchhoff diffraction theory that is derived for general configurations in which a spherical reference is employed.

Phase-shifting color digital holography.
TL;DR: Compared the images reconstructed by two algorithms using a single Fourier transformation and a convolution with each other by both experiments and numerical simulations have proved not to cause serious deterioration of the reconstructed images.
