Exploring student perceptions of integrating mixed reality with cadaveric teaching in undergraduate neuroanatomy education: A qualitative study

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Mixed reality (MR) using head‐mounted displays provides three‐dimensional visualizations that have been suggested to enhance learning when used alongside conventional anatomy teaching in medical education. This study explored student perceptions of the integration of MR and traditional cadaveric learning, and their optimal delivery to support ...

Metasurface orbital angular momentum holography

open access: yesNature Communications, 2019
Conventional hologram designs lack orbital angular momentum selectivity. Here, the authors design metasurface holograms consisting of GaN nanopillars with discrete spatial frequency distributions allowing the reconstruction of distinctive orbital angular

Refractive Index–Correlated Pseudocoloring for Adaptive Color Fusion in Holotomographic Cytology

open access: yesCytometry Part A, EarlyView.
ABSTRACT Conventional bright‐field (BF) cytology of thyroid fine‐needle aspiration biopsy (FNAB) suffers from staining variability and limited subcellular contrast. Here, we present a refractive index–correlated pseudocoloring (RICP) framework that integrates quantitative refractive index (RI) maps obtained by holotomography (HT) with color BF images ...

A new approach for three-dimensional atomic-image reconstruction from a single-energy photoelectron hologram

open access: yes, 2004
A “scattering pattern matrix” method is proposed here to overcome the difficulties presented by photoelectron holography, such as forward-scattering and multi-energy problems.

Photothermal bubble: Dynamics, manipulation, and applications

open access: yesDroplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

PEMBUATAN HOLOGRAM TRANSMISI [PDF]

open access: yes, 2004
A transmission hologram of white ceramic as cat statue has been made on 5000 lines/mm Agfa Geveart. By recording of hologram, the average and optimal exposure time lies between 8 and 10 seconds, it is used He-Ne laser (l = 632.8 nm).

Multi-depth phase-only hologram optimization using the L-BFGS algorithm with sequential slicing.

open access: yes, 2023
We implement a limited-memory Broyden-Fletcher-Goldfarb-Shanno (L-BFGS) optimization of phase-only computer-generated hologram for a multi-depth three-dimensional (3D) target.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Effects of Irregular Bathymetry on Hologram Formation of Moving Source in Shallow Water

open access: yesJournal of Marine Science and Engineering
This paper examines the effect of irregular bathymetry on the holographic reconstruction of the sound field generated by a moving source in shallow water. In this scenario, acoustic waves propagate along the path between the source and receiver.
