Advances in Digital Holographic Interferometry [PDF]

open access: yesJournal of Imaging, 2022
Holographic interferometry is a well-established field of science and optical engineering. It has a half-century history of successful implementation as the solution to numerous technical tasks and problems. However, fast progress in digital and computer

Digital Holographic Interferometry for the Measurement of Symmetrical Temperature Fields in Liquids

open access: yesPhotonics, 2021
In this paper, we present a method of quantitatively measuring in real-time the dynamic temperature field change and visualization of volumetric temperature fields generated by a 2D axial-symmetric heated fluid from a pulsatile jet in a water tank ...

Holographic Interferometry for Measuring the Effect of Thermal Modification on Wood Thermal Properties

open access: yesApplied Sciences, 2021
The paper focuses on the use of holographic interferometry in the research of thermal modification and its effect on the heat transfer from the wood surface to the surrounding air. In the experiment, spruce wood samples modified at 160 °C, 180 °C, 200 °C,

Cortical bone quality affectations and their strength impact analysis using holographic interferometry. [PDF]

open access: yesBiomed Opt Express, 2018
It is now accepted that bone strength is a complex property determined mainly by three factors: quantity, quality and turnover of the bone itself. Most of the patients who experience fractures due to fragility could never develop affectations related to ...

Holographic interferometry for the study of liquids [PDF]

open access: yesJournal of Molecular Liquids 134 (2007) 8-14, 2009
Holography is an optical technique enabling to record phase objects. Holographic interferometry uses this faculty to make a phase object interfere with a memory of itself at a preceding time, recorded on a hologram. Interference fringes therefore inform on any variation of the phase of the object.

Photoelectron holographic interferometry to probe the longitudinal momentum offset at the tunnel exit [PDF]

open access: yesPhys. Rev. Lett. 122, 183202 (2019), 2019
Laser-induced electron tunneling underlies numerous emerging spectroscopic techniques to probe attosecond electron dynamics in atoms and molecules. The improvement of those techniques requires an accurate knowledge of the exit momentum for the tunneling wave packet.

Incoherent Holographic Interferometry [PDF]

open access: hybrid, 2011
The original meaning of coherence was attributed to the ability of light to exhibit interference phenomena. There are two types of coherence: temporal coherence and spatial coherence. Temporal coherence measures the ability of two relatively delayed beams to form interference fringe.

Level of holographic noise in interferometry [PDF]

open access: yesPhys.Rev.D79:087503,2009, 2009
The level of holographic noise expected to be observed in interferometric gravitational wave detectors such as GEO600 is re-examined. It is demonstrated that earlier estimates are based on assumed linear diffractive behavior of Planck radiation. Since nonlinear effects, such as self-focusing, are expected to appear at much lower energies, the expected ...

Quantitative phase microscopies: accuracy comparison. [PDF]

open access: yesLight Sci Appl
This article presents a thorough comparison of themain QPM techniques, focusing on their accuracy in terms of measurement precision and trueness. We focus on 8 techniques, namely digital holographic microscopy (DHM), cross-grating wavefront microscopy (CGM), which is based on QLSI (quadriwave lateral shearing interferometry), diffraction phase ...
