Zooming algorithms for Digital Holography

open access: yesJournal of Physics: Conference Series, 2010
Digital Holography is an imaging modality made up of two parts: (1) using a digital camera to record the interference pattern between a field scattered from an object and a known reference field so that the complex object wavefield can be obtained and (2) replaying or reconstructing the hologram on a computer by simulating the propagation of the object

Single-shot wavelength-multiplexed digital holography for 3D fluorescent microscopy and other imaging modalities

open access: yes, 2020
We propose a holographic technique by which multiwavelength three-dimensional spatial information is obtained with both a single-shot exposure of a monochrome image sensor and an in-line holographic multiplexing scheme.

Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation

open access: yesETRI 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.

Applications of Digital Holography: From Microscopy to 3D-Television [PDF]

open access: yesJournal 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 ...

Imaging velocities of a vibrating object by stroboscopic sideband holography [PDF]

open access: yes, 2012
We propose here to combine sideband holography with stroboscopic illumination synchronized with the vibration of an object. By sweeping the optical frequency of the reference beam such a way the holographic detection is tuned on the successive sideband ...

Multiwavelength-multiplexed phase-shifting incoherent color digital holography.

open access: yesOptics Express, 2020
We propose multiwavelength-multiplexed phase-shifting incoherent color digital holography. In this technique, a monochrome image sensor records wavelength-multiplexed, phase-shifted, and incoherent holograms, and a phase-shifting interferometry technique

Digital phase conjugation of second harmonic radiation emitted by nanoparticles in turbid media [PDF]

open access: yes, 2010
We demonstrate focusing coherent light on a nanoparticle through turbid media based on digital optical phase conjugation of second harmonic generation (SHG) field from the nanoparticle.

Performance analysis of phase retrieval using transport of intensity with digital holography [Invited].

open access: yesApplied Optics, 2020
The performance of direct and unwrapped phase retrieval, which combines digital holography with the transport of intensity, is examined in detail in this paper.

Iterative phase retrieval for digital holography: tutorial. [PDF]

open access: yesJournal of The Optical Society of America A-optics Image Science and Vision, 2019
This paper provides a tutorial of iterative phase retrieval algorithms based on the Gerchberg-Saxton (GS) algorithm applied in digital holography. In addition, a novel GS-based algorithm that allows reconstruction of 3D samples is demonstrated.

Digital Holographic Printing Methods for 3D Visualization of Cultural Heritage Artifacts

open access: yesDigital 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 ...
