Holographic Video Microscopy for Biology
Frontiers in Optics 2008/Laser Science XXIV/Plasmonics and Metamaterials/Optical Fabrication and Testing, 2008We present the use of holographic video microscopy for extracting quantitative data from digitized video holograms of colloidal suspensions in biological sample. Holographic video microscopy offers both multiple particles three-dimensions tracking and particle characterization concurrently.

A Single-Chip FPGA Holographic Video Processor
IEEE Transactions on Industrial Electronics, 2019In this paper, we present the world's first single-chip field-programmable gate array holographic video processor. It makes 16 computer-generated color holograms of resolution 1920 × 1080 in a second. It uses an off-the-shelf commercial liquid crystral display for the spatial light modulator.

Holographic video disk: an alternative approach to optical video disks
Applied Optics, 1976Optical video disks employing time sequential coding are superior to mechanical video disks because of their noncontact reproducing capability. One drawback in the optical systems is the necessity of precise focusing and tracking adjustments. To solve this problem, an alternative approach, using a holographic technique that makes it possible to store a

SPIE Proceedings, 1993
We discuss recent developments in the MIT electronic holography display. These include the use of multiple galvanometric scanners as the horizontal scanning element, two 18-channel acousto-optic modulators (AOM's) working in tandem, and a bank of custom-designed high- bandwidth framebuffers. We also describe some recent progress on computational issues.

Wide angle holographic video projection display
Optics Letters, 2021Holographic projection displays provide high diffraction efficiency. However, they have a limited projection angle. This work proposes a holographic projection display with a wide angle, which gives an image of size 306 m m × 161 m m at 700 mm and reduced speckle noise. The solution uses single

Digital holographic video of plankton
SPIE Proceedings, 2008The use of digital holography for plankton detection is discussed, namely - for evaluation of the plankton particles shapes, orientation, and 3-D location. Algorithms are considered for improve the quality of the reconstructed plankton holographic image. The algorithms are based on the digital hologram pre-processing before reconstruction.

2011 International Conference on 3D Imaging (IC3D), 2011
Device for presenting 3D animated images, obtained by taking pictures through a diffraction grating, from all size objects, and a projection onto a holographic screen. The diffraction, orientated horizontally, gets by each ray of light a way done which depends on its wavelength and allows to obtain as many angles of vision as wavelengths.
