Digital holography - an innovative technology for analysis of living cells
Bioingeniøren, 2010 Background: Digital holography is a novel technique which has been used for about five years to study living cells. The technique is an innovative, non-destructive method with possibilities to study living cells over time.

Complexity of warped conformal field theory
European 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 ...

The investigation of volume change of photopolymerization by holography.
Journal 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.

Early cell death detection with digital holographic microscopy.
PLoS ONE, 2012 BackgroundDigital holography provides a non-invasive measurement of the quantitative phase shifts induced by cells in culture, which can be related to cell volume changes.

Laser &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 ...

Holographic complexity and volume
Journal 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

Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures
Laser &Photonics Reviews, EarlyView.A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency
