A Regularized Inverse Holographic Volume Reconstruction (RIHVR) GUI Program for Digital Inline Holography (DIH)

open access: yesJournal of Open Research Software
Digital inline holography is a well-established experimental technique used to capture three-dimensional (3D) information from a scene onto a two-dimensional image using a single camera.

Complexity of warped conformal field theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Warped conformal field theories in two dimensions are exotic nonlocal, Lorentz violating field theories characterized by Virasoro–Kac–Moody symmetries and have attracted a lot of attention as candidate boundary duals to warped AdS $$_3$$ 3 spacetimes ...

Measurement of cell volume using in-line digital holography

open access: yesMicroscopy, 2020
Abstract The measurement of the volume of blood cells is important for clinical diagnosis and patient management. While digital holography microscopy has been used to obtain such information, previous off-axis setups usually involve a separated reference beam and are thus not very easy to implement.

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Holographic complexity and volume

open access: yesJournal of High Energy Physics, 2018
The previously proposed “Complexity=Volume” or CV-duality is probed and developed in several directions. We show that the apparent lack of universality for large and small black holes is removed if the volume is measured in units of the maximal time from

Bayesian Optimization of Grayscale Patterns for Layer‐Height Accuracy in Projection Multi‐Photon 3D Printing

open access: yesLaser &Photonics Reviews, EarlyView.
Bayesian optimization combined with in situ quantitative phase imaging enables autonomous correction of layer‐height deviations in projection multi‐photon lithography. By jointly tuning model parameters and grayscale exposure settings, the method achieves more uniform and accurate layers within 300 prints, offering a fast, data‐efficient route to ...

The investigation of volume change of photopolymerization by holography.

open access: yesJournal of Photopolymer Science and Technology, 1992
The volume of a photopolymerizable medium may be changed after monomer is converted into polymer. One has not yet precise method for measuring a volume change when a photopolymerization reaction occurs in a film. This paper proposes a holographic method for measuring the volume change (that is the thickness change) of a photopolymerizable film.
