IEEE Princeton/Central Jersey Sarnoff Symposium,, 2005
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 (AOMs) working in tandem, and a bank of custom-designed high-bandwidth framebuffers.

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.

Experiments in holographic video imaging
SPIE Proceedings, 1990Reduction of the information content of a hologram to the minimum necessary to support strong spatial perception makes possible the interactive computation, transmission, and display of three-dimensional animated holographic images.

Past, current, and future of holographic video display [Invited]
Applied Optics, 2021Holography has been considered as the ultimate technology for three-dimensional visual experience. Compared to the well-established static holographic technology, holographic video display is still in the research and development stage, before commercial products.

Temporal Consistency Enhancement for Digital Holographic Video
2015Holography is an imaging technique to reconstruct wavefront information of the light scattered by real objects or a scene, allowing an observer to perceive three-dimensional 3D images with the unassisted eye. Such 3D holographic images result from reproducing the intensity and phase of light by diffraction.

Holographic Video System with a Pulse Laser
Japanese Journal of Applied Physics, 1998A holographic video system operated by a pulse laser is described. The use of a pulse laser as the light source allows the polygon mirror (or scanners) in the system to be eliminated. At the same time, a single long aperture acousto-optic modulator (AOM) is replaced by 6 small aperture AOMs linearly aligned and a still polygon mirror set ...

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.

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 ...

HOLOGRAPHIC VIDEO: The ultimate visual interface?
Optics and Photonics News, 1997While holographic video is a realistic concept in contemporary science fiction, it remains an illusive technology. St. Hilaire discusses the need for advanced visual interfaces, and explains the history, present state, and future of the technology, with an emphasis on the MIT Media Laboratory project.
