DEPTHQ® HD 3D PROJECTOR AND NVIDIA® 3D VISION™ SUPPORT NEUROBIOLOGY RESEARCH OF 3D MOTION PERCEPTION

Drs. Bas Rokers (pictured below), Alex Huk and Larry Cormack, Neurobiology researchers at the University of Texas at Austin, are utilizing a DepthQ® HD 3D projector along with NVIDIA® 3D Vision™ to present their studies of how the human brain perceives 3D motion. "We perceive motion in three dimensions, even though each eye only receives a two dimensional image. How does our brain combine the two images into a 3D percept?" Click How the Brain Sees 3D for a YouTube video illustrating this concept.

LIGHTSPEED'S POLARIZATION ROTATOR, DEPTHQ® HD 3D 4000 LUMEN PROJECTOR & FLASH BASED DEPTHQ®s3D WebPlayer™ FEATURED IN THE "LARGE DISPLAY REPORT"

September 2009 - Lightspeed Design, Inc. has 3 new products featured in the September 2009 Issue (Volume 7 - No. 9) of the Large Display Report, a subscription based, monthly newsletter covering Technology, Product, Market and Business News and Analysis for Large Area Display Systems, Components, and Supply Chain.

400 Hz Polarization Rotator Comes to US
Arthur Berman and Matthew Brennesholtz

3D projector supplier Lightspeed Design (Bellevue, WA) and LC-Tec Displays AB (Borlänge, Sweden) have signed a new agreement that grants Lightspeed the exclusive rights to market and sell high-speed liquid crystal polarization rotator devices manufactured by LC-Tec Displays AB for stereoscopic 3D visualization products.

LC-Tec Displays developed a new type of liquid crystal polarization rotator that is capable of switching the polarization of a projected image at a speed of 400 Hz. Drive voltage is a 24V square wave. With the optional input polarizer, the system can produce two orthogonal polarizations output from unpolarized input light. One major application of the device is to be used with an unpolarized projector to produce 3D that can be viewed with either linear- or circular-polarized passive viewing glasses.

An engineering prototype of the new polarization rotator was demonstrated at the recent SIGGRAPH 2009.

Also launched at SIGGRAPH was a new high-brightness Lightspeed Design - InFocus DepthQ HDs3D stereoscopic projector. Ward said top level specifications for the new projector include:

• WXGA (1280 x 720/120p)
• 4K ANSI lumens
• 120 Hz page-flip S-3D
• Centered lens, two-axis lens shift
• VGA and HDMI input
• Keystone/pincushion/barrel distortion correction

Anaglyph 3D: Problems and Solutions
Arthur Berman

Recent Developments

Lightspeed Design (Bellevue, WA) has developed a flash technology for anaglyph delivery. In an email exchange with Chris Ward, the president of Lightspeed, we learned that this is not an ordinary red/blue or red/cyan mix but, rather, an improved mix that the company has been working on for about a year. Both the flash delivery container and anaglyph process are reported to be special. A video containing a demonstration of images presented in the new anaglyph mode is available online.

DEPTHQ® HD 3D PROJECTOR UTILIZED IN DEVELOPMENT OF 3D SURGERY VISUALIZATION

Led by Prof. Dr. Erich Sorantin, an interdisciplinary team of radiologists, surgeons and engineers in Austria are using the DepthQ® HD 3D projector in their development of the "Virtual Liver Surgery Planning System" (VLSPS). Based on S-CT imaging in combination with 3D and Virtual Reality techniques, the VLSPS will provide more accurate liver and tumor volume data as well as offer better communication between radiologists and non-radiologists.
