Near-perfect hologram reconstruction with a spatial light modulator.
Optics Express, 2008 We present an implementation method for noiseless holographic projection of precalculated light fields with a spatial light modulator. In the reconstructed image, both the spatial amplitude and phase distributions can be programmed independently. This is

Structured transmittance illumination coherence holography
Scientific Reports, 2022 The coherence holography offers an unconventional way to reconstruct the hologram where an incoherent light illumination is used for reconstruction purposes, and object encoded into the hologram is reconstructed as the distribution of the complex ...

Advanced Intelligent Systems, EarlyView.A 3D holotomography system coupled with a deep learning model distinguishes how cells die—apoptosis, necroptosis or necrosis—without any fluorescent labels. Training on refractive index maps of HeLa cells yields 97% accuracy and flags necroptosis hours before chemical dyes.

Holographic analysis of diffraction structure factors
, 2002 We combine the theory of inside-source/inside-detector x-ray fluorescence holography and Kossel lines/x ray standing waves in kinematic approximation to directly obtain the phases of the diffraction structure factors.

One Metasurface for Four‐Channel Terahertz Wavefront Manipulation Based on Vanadium Dioxide
Advanced Physics Research, EarlyView.This article presents a thermally reconfigurable metasurface utilizing vanadium dioxide (VO2) to dynamically switch between four independent wavefront‐manipulation channels. By synergizing geometric and propagation phases, the platform enables spin‐decoding for circularly polarized waves and polarization multiplexing for linearly polarized waves ...
