Quantifying Particle Volumes with Photon-counting Digital Holography
, 2023 We propose a photon-counting digital holography method to accurately reconstruct particle volumes in low light conditions. Our approach integrates a Poisson digital holography model into an unrolled network, overcoming the challenges of shot noise and ...

Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation
ETRI Journal, 2019 Holography has been fascinating people for almost 70 years (since Gabor's invention in 1947) as a true three‐dimensional (3D) imaging technology that can replicate 3D scenes in free space.

Digital Holographic Printing Methods for 3D Visualization of Cultural Heritage Artifacts
Digital Presentation and Preservation of Cultural and Scientific Heritage, 2014 Holography enables capture and reconstruction of the optical field scattered from three-dimensional (3D) objects. The hologram encodes both amplitude and phase of the field under coherent illumination, whereas photography records only the amplitude by ...

Applications of Digital Holography: From Microscopy to 3D-Television [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 The paper gives an overview of the applications of digital holography based on the one hand on CCD-recording, computer storage, and numerical reconstruction of the wave fields, and on the other hand on numerical calculation of computer generated ...

Grid computing for the numerical reconstruction of digital holograms
, 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 ...

Edge-preserving autofocusing in digital holography
, 2016 In digital holography, it is essential to know the axial position of the recorded object for reconstruction. Here we propose an autofocusing algorithm using structure tensor to determine the focal distance and to extract the edge information ...
