Study on Quantitative Phase Imaging by Dual-Wavelength Digital Holography Microscopy

open access: yesInternational Journal of Optics, 2018
A dual-wavelength digital holographic microscopy with premagnification is proposed to obtain the object surface measurements over the large gradient. The quantitative phase images of specimens are captured in high precision by the processing of filtering

Digital Holographic Microscopy

open access: yesMicroscopy and Microanalysis, 1999
Abstract We applied phase-shifting digital holography to microscopy in this paper. At first lensless microscopy is proposed, in which no optical adjustment is necessary. Then, the method is applied to relax the limitation of focal depth in traditional optical microscopy.

On-Axis Digital Holographic Microscopy: Current Trends and Algorithms

open access: yesOptics Communications, 2023
Digital holographic microscopy (DHM) is a rapidly developing imaging technique that allows for the reconstruction of three-dimensional images from holographic data. In this review paper, we present an overview of the state-of-the-art in on-axis DHM reconstruction methods.

Grid computing for the numerical reconstruction of digital holograms

open access: yes, 2005
Digital holography has the potential to greatly extend holography's applications and move it from the lab into the field: a single CCD or other solid-state sensor can capture any number of holograms while numerical reconstruction within a computer ...

Single-shot digital holographic microscopy based on computational telecentricity using a single-arm off-axis interferometer

open access: yesICT Express, 2018
We propose a single-shot digital holographic microscopy based on computational telecentricity with a single-arm off-axis interferometer (SA-OAI), which is composed of optical recording, computational compensation and retrieving processes.

Opposite-view digital holographic microscopy with autofocusing capability

open access: yesScientific Reports, 2017
Digital holographic microscopy (DHM) has its intrinsic ability to refocusing a sample by numerically propagating an object wave from its hologram plane to its image plane.

Automatic cross filtering for off-axis digital holographic microscopy

open access: yesResults in Physics, 2020
Off-axis digital holographic microscopy (DHM) is a significant quantitative phase imaging (QPI) modality in a single shot. However, the reconstructed quality of the image in the off-axis DHM is governed by the spatial filtering in the spectral domain of ...
