Video Holographic Interferometry
SPIE Proceedings, 1987A description is given of the history and principal developers of the technique of T.V. Holographic Interferometry. The principles of the method are next outlined and recent work involving the use of pulsed holographic lasers combined with a C.O.D. video holographic interferometer is described as applied to the study of automobile disk brakes rotor ...

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

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.

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.

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.

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 ...
