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 ...

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.

Feed particle size evaluation: conventional approach versus digital holography based image analysis

open access: yesItalian Journal of Animal Science, 2010
The aim of this study was to evaluate the application of image analysis approach based on digital holography in defining particle size in comparison with the sieve shaker method (sieving method) as reference method.

Multi-Object Deep-Field Digital Holographic Imaging Based on Inverse Cross-Correlation

open access: yesApplied Sciences, 2023
To address the complexity of small or unique reconstruction distances in digital holography, we propose an inverse cross-correlation-based algorithm for the digital holographic imaging of multiplanar objects with a large depth of field. In this method, a

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.
