A first embodiment of the invention permits an extension of battery life through detection of the display synchronization signals of a computer and a power management system. The power management system also eliminates need for batteries through use of a 5V power source from pin 9 of the VGA port. A second embodiment improves the ease of use and the utility of the 3D system through removable glasses with improvements over the previous design. These embodiments have improved manufacturability through the use of design that is tolerant of poor quality, low cost components with low electrical tolerances.

The invention is a stereoscopic shutter system having a single liquid crystal (LC) cell. The system may have flexible substrates or non-flexible substrates. The system requires only two electrical conductors to shutter both eyes. The system uses twisted nematic liquid crystal, ferro-electric liquid crystal, pi-cell technology, or other similar shuttering technologies. The system includes only one LC cell, a single large laminated linearly polarizing filter P1, and two smaller linear polarizing analyzers oriented in the P1 and P2 states. The shutters may be bent into a one-dimensional curved shape about the vertical or horizontal axis.

The invention is a method for creating a micropolarizer, including providing a first plate having a first and a second surface, providing a second plate having a first and a second surface. Then coating a polyimide on each of the first surface of the two plates followed by rubbing the polyimide coated upon the first surface of the first plate along a predetermined direction and rubbing the polyimide coated upon the first surface of the second plate along a direction having a predetermined angle in relation to the predetermined direction. An alignment process includes aligning the first plate and the second plate having the first surface of the first plate and the first surface of the second plate facing each other thereby creating a space there between. In conclusion there is a filling of a liquid crystal material in the space whereby a cell, or film is created.

The present invention utilizes a new and inexpensive method for stereoscopic demultiplexing from a single computer data source. The invention provides a means to switch the routing of left and right image data, if necessary. Additionally the invention provides for an internal swap of the green data signal between the two channels permitting the device to be used with polarized output projection systems in which the green light output is polarized orthogonally to the red and blue light output.

The preferred embodiment addresses the problem of delivering stereoscopic media in electronic form (images, videos, animations, object models, etc.). First, it provides a single format with independent right and left channels to represent the stereoscopic media. Second, it provides a means of displaying stereoscopic media inside a movable windowed area while eliminating pseudostereo conditions during movement. Third, it provides automatic and manual optimization adjustments (parallax shift adjustment, brightness control, color adjustment, and cross-talk reduction) to the stereoscopic media based on viewing hardware, monitor size, and media content for optimal viewing quality. Fourth, it provides seamless support for monoscopic (2D) viewing modes allowing delivery of said stereoscopic media in a normal 2D viewing mode.

An intelligent system and process for producing and displaying stereoscopically-multiplexed images of either real or synthetic 3-D objects, for use in realistic stereoscopic viewing thereof. The system comprises a subsystem for acquiring parameters specifying the viewing process of a viewer positioned relative to a display surface associated with a stereoscopic display subsystem. A computer-based subsystem is provided for producing stereoscopically-multiplexed images of either the real or synthetic 3-D objects, using the acquired parameters. The stereoscopically-multiplexed images are on the display surface, for use in realistic stereoscopic viewing of either the real or synthetic 3-D objects, by the viewer.

The present invention provides a means to augment or upgrade a traditional single beam 2D x-ray system to produce 3D stereoscopic output. The system utilizes the cross-sectional beam divergence of a single source x-ray unit to generate perspective information. This is achieved by scanning the object twice where the object is shifted parallel to the cross-sectional beam plane between scans. The resulting two scans can be displayed on a 3D stereoscopic viewing system to produce a 3D stereoscopic representation of the object thus revealing all three-depth dimensions. The invention includes a method of converting a 2D x-ray system to a 3D x-ray system requiring no changes to an x-ray generation portion, optics portion or sensing system portion of said 2D x-ray system. The method includes coupling a 3D stereoscopic image processor to a 2D processor and installing a mechanical shift system and coupling said shift system to said 3D stereoscopic image processor and a object carrying device.

The present invention relates to a system and method of viewing pairs of perspective images of 3-D objects (i.e. stereoscopic image pairs) displayed from a CRT display surface in a time-multiplexed or field-sequential manner, and more particularly to a universal method of generating control signals for synchronously changing the optical state of liquid crystal (LC) shutter panels through which the time-multiplexed perspective images can be sequentially viewed in a substantially flicker-free manner by the left and right eyes of a human viewer, independent of whether the images are displayed on NTSC, PAL, VGA or SVGA styled CRT display devices.
