Deep DIH: Single-Shot Digital In-Line Holography Reconstruction by Deep Learning
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 ...

Noise minimised high resolution digital holographic microscopy applied to surface topography [PDF]
The topography of surface relief gratings was studied by digital holographic microscopy. The applicability of the method for quantitative measurements of surface microstructure at nanoscale was demonstrated.

Magnetic Holography and Its Application to Data Storage
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 ...

High numerical aperture holographic microscopy reconstruction with extended z range [PDF]
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 ...

Holographic microscopy reconstruction in both object and image half spaces with undistorted 3D grid [PDF]
We propose an holographic microscopy reconstruction method, which propagates the hologram, in the object half space, in the vicinity of the object. The calibration yields reconstructions with an undistorted reconstruction grid i.e.

Challenges in using GPUs for the real-time reconstruction of digital hologram images [PDF]
This is the pre-print version of the final published paper that is available from the link below.In-line holography has recently made the transition from silver-halide based recording media, with laser reconstruction, to recording with large-area pixel ...

Dual wavelength digital holography for 3D particle image velocimetry [PDF]
A multi-exposure digital in-line hologram of a moving particle field is recorded by two different wavelengths and at different times. As a result, during the reconstruction step, each hologram can be independently and accurately reconstructed for each ...
