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 ...

Video-rate computational heterodyne holography [PDF]
Optics Letters, 2014 We present a versatile computational image rendering software of optically-acquired holograms. The reported software can process 4 Megapixel 8-bit raw frames from a sensor array acquired at a sustained rate of 80 Hz. Video-rate image rendering is achieved by streamline image processing with commodity computer graphics hardware.

Advanced Science, EarlyView.Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.

Circle of holography : digital in-line holography for imaging, microscopy and measurement
, 2006 Gabor proposed the concept of holography for wavefront reconstruction. The advent of the laser enabled Leith et al. to develop this concept into a technology with off-axis holography. Advances in computational methods and better digital recording medium,

Lattice holography on a quantum computer
Physical Review DWe explore the potential application of quantum computers to the examination of lattice holography, which extends to the strongly coupled bulk theory regime. With adiabatic evolution, we compute the ground state of a spin system on a ( 2 +

Advanced Science, EarlyView.Launching structures for in‐plane hyperbolic polaritons in α‐MoO3 are optically programmed through already deposited flakes into the phase‐change material In3SbTe2. Precise alignment with the flake's crystal axes, focusing of polaritons by an optically programmed disk, and a first experimental realization toward a nanocavity for in‐plane hyperbolic ...

Holography : an interpretation from the phase-space point of view [PDF]
, 2007 The formation of holograms is interpreted as the consequence of the bilinearity of the ambiguity function. Reconstruction can then be regarded as the manipulation of the ambiguity function.
