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.

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.

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.

Toward Interactive Holographic Video Imaging
Optics in Computing, 1997Electronic holographic imagingis a truly three-dimensional real-time digital imaging medium. Recent progress in holographic video has demonstrated that the crucial technologies—computation, electronic signal manipulation, and optical modulation & scanning—may be scaled up to produce larger, more interactive, full-color holographic images.

New approaches to holographic video
Optical Society of America Annual Meeting, 1992The MIT holographic video system has displayed color holograms of excellent quality but is limited in its present implementation to images of a few tens of millimeters on a side. This limitation is a consequence of using a polygonal mirror as a horizontal scanning element.

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

High-Performance Digital Holographic Video System
Digital Holography and Three-Dimensional Imaging, 2013We propose a new system which can generate digital holograms using natural color information. The proposed system can generate about 10 digital holographic video frames per a second using about 6K light sources.

Anisotropic leaky-mode modulator for holographic video displays
Nature, 2013Every holographic video display is built on a spatial light modulator, which directs light by diffraction to form points in three-dimensional space. The modulators currently used for holographic video displays are challenging to use for several reasons: they have relatively low bandwidth, high cost, low diffraction angle, poor scalability, and the ...
