Wavefront division digital holography

open access: yesAIP Advances, 2018
Digital holography (DH), mostly Mach-Zehnder configuration based, belongs to non-common path amplitude splitting interference imaging whose stability and fringe contrast are environmental sensitive.

Phase‐Retrieved High‐Throughput Multi‐Channel Simultaneous Surface Plasmon Resonance Detection

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a new phase‐retrieval high‐throughput multi‐channel simultaneous SPR detection framework. By integrating an objective lens‐based coupling system with a rotation‐based ePIE (r‐ePIE) phase retrieval on the back focal planes, this framework significantly reduces the minimum required detection area to reveal localized information.

Nonlinear Digital Holography

open access: yesBiomedical Optics and 3-D Imaging, 2010
We extend digital holography, and the techniques of computational imaging in general, to beam propagation in nonlinear media. Nonlinearity mixes high-frequency spatial modes with low-frequency ones, so that reconstruction results in super-resolution of the object.

Learning-based nonparametric autofocusing for digital holography

open access: yes, 2018
In digital holography, it is crucial to extract the object distance from a hologram in order to reconstruct its amplitude and phase. This is known as autofocusing, which is conventionally solved by first reconstructing a stack of images, and then the ...
