High numerical aperture holographic microscopy reconstruction with extended z range [PDF]
, 2015 An holographic microscopy reconstruction method compatible with high numerical aperture microscope objective (MO) up to NA=1.4 is proposed. After off axis and reference field curvature corrections, and after selection of the +1 grating order holographic ...

Hologram conversion for speckle free reconstruction using light field extraction and deep learning.
Optics Express, 2020 A novel hologram conversion technique for speckle-less reconstruction is proposed. Many speckle-less reconstruction methods require holograms specially created for those techniques, limiting their applications to general pre-existing holograms.

Compression of Phase-Only Holograms with JPEG Standard and Deep Learning
Applied Sciences, 2018 It is a critical issue to reduce the enormous amount of data in the processing, storage and transmission of a hologram in digital format. In photograph compression, the JPEG standard is commonly supported by almost every system and device.

Deep DIH: Single-Shot Digital In-Line Holography Reconstruction by Deep Learning
IEEE Access, 2020 Digital in-line holography (DIH) is broadly used to reconstruct 3D shapes of microscopic objects from their 2D holograms. One of the technical challenges in the reconstruction stage is eliminating the twin image originating from the phase-conjugate ...

Holographic particle localization under multiple scattering [PDF]
, 2019 We introduce a novel framework that incorporates multiple scattering for large-scale 3D particle-localization using single-shot in-line holography. Traditional holographic techniques rely on single-scattering models which become inaccurate under high ...

Practical algorithms for simulation and reconstruction of digital in-line holograms [PDF]
, 2015 Here we present practical methods for simulation and reconstruction of in-line digital holograms recorded with plane and spherical waves. The algorithms described here are applicable to holographic imaging of an object exhibiting absorption as well as ...

Magnetic Holography and Its Application to Data Storage
Photonics, 2021 The principle of magnetic holograms and its application to holographic memory are reviewed. A magnetic hologram was recorded through a thermomagnetic recording as a difference in magnetization direction and reconstructed with the magneto-optical effect ...

Absorbing new subjects: holography as an analog of photography [PDF]
, 2006 I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of Dennis Gabor (1900–1979) in England,Yury N. Denisyuk (1927-2005) in the Soviet Union,
