Incoherent Digital Holography: A Review

open access: yesApplied Sciences, 2018
Digital holography (DH) is a promising technique for modern three-dimensional (3D) imaging. Coherent holography records the complex amplitude of a 3D object holographically, giving speckle noise upon reconstruction and presenting a serious drawback ...

Digital Plasmonic Holography [PDF]

open access: yesImaging and Applied Optics 2018 (3D, AO, AIO, COSI, DH, IS, LACSEA, LS&C, MATH, pcAOP), 2018
AbstractWe demonstrate digital plasmonic holography for direct in-plane imaging with propagating surface-plasmon waves. Imaging with surface plasmons suffers from the lack of simple in-plane lenses and mirrors. Lens-less digital holography techniques, however, rely on digitally decoding an interference pattern between a reference wave and an object ...

Robust Holographic Reconstruction by Deep Learning with One Frame

open access: yesPhotonics, 2023
A robust method is proposed to reconstruct images with only one hologram in digital holography by introducing a deep learning (DL) network. The U-net neural network is designed according to DL principles and trained by the image data set collected using ...

Undersampled digital holography

open access: yesOptics Express, 2009
Acceptable signal recovery of the band-pass signals typically used in the off-axis digital holography systems is possible in the undersampling conditions. A typical system is considered in which the angle between two beams represents a variable parameter.

Based on incoherent spatial light modulator telescopic experimental research of digital holographic imaging system about “White light”

open access: yesResults in Optics, 2021
At present, there are few researches about telescopic digital holography (TDH) on the combination of digital holography and telescope technology. Because this technology generally cause low phase shift accuracy and large image reconstruction distance ...

Digital holography with microcombs [PDF]

open access: yesEPJ Web of Conferences, 2023
Optical microresonators are attractive comb sources due to their small form factor and stable broad optical spectra. We report on the first demonstration of microcomb-based digital holography.

Compressive Holographic Video [PDF]

open access: yes, 2016
Compressed sensing has been discussed separately in spatial and temporal domains. Compressive holography has been introduced as a method that allows 3D tomographic reconstruction at different depths from a single 2D image.

Shot Noise in Digital Holography [PDF]

open access: yes, 2010
We discuss on noise in heterodyne holography in an off-axis configuration. We show that, for a weak signal, the noise is dominated by the shot noise on the reference beam.
