This Roadmap article on digital holography provides an overview of a vast array of research
activities in the field of digital holography. The paper consists of a series of 25 sections from …

We report a method for two-dimensional phase unwrap** based on the transport of
intensity equation (TIE). Given a wrapped phase profile, we generate an auxiliary complex …

Low-light imaging is challenging in regimes where low-noise detectors are not yet available.
One such regime is the shortwave infrared where even the best multipixel detector arrays …

Sensors based on single spins can enable magnetic-field detection with very high sensitivity
and spatial resolution. Previous work has concentrated on sensing of a constant magnetic …

Off-axis digital holograms are commonly processed using the Fourier transform method. This
method requires estimation of the carrier frequency peak in the two-dimensional Fourier …

We report results on unsupervised organization of cervical cells using microscopy of Pap‐
smear samples in brightfield (3‐channel color) as well as high‐resolution quantitative phase …

Given the fact that the cellular interior is crowded by many different kinds of macromolecules,
it is important that in vitro studies be carried out in the presence of mixed crowder systems. In …

We examine the nature of the reconstructed 3D image as obtained by replay (or back-
propagation) of the object wave from the hologram recording plane to the original object …

We describe a constrained optimization approach for demodulation of single-shot
interferograms corresponding to step phase objects. The demodulation problem is …

Complex object wave recovery from a single-shot interference pattern is an important
practical problem in interferometry and digital holography. The most popular single-shot …
