    Abstract: Apparatus and method for the display of autostereoscopic images, in which two or more perspective views are generated by a single transmissive display screen, is provided. A structured light source behind the screen directs light through different sets of display elements to correspondingly different viewing zones. In certain embodiments, the structured source comprises a patterned mask which prevents light from passing through a particular set of elements and reaching the wrong zone. The pattern of the mask may be programmed. Observer co-ordinate data permits the correct viewing zone to be co-located with each of the observer's corresponding eyes. A tapered lenticular structure can provide the means for adapting to changes in the observer's distance from the display. In further embodiments a holographic optical element (HOE) may be used instead of an array of conventional lens elements. The HOE typically incorporates the function of providing in conjunction with a suitably located light source the viewing zones required for respective sets of display elements. The display may also be used to provide conventional two-dimensional images at the display screen's full resolution.

    Abstract: Apparatus and method for the alignment of images in which, typically, two perspective views are provided. The observer's head location is detected and each of the views is presented to the respectively correct eye to provide a stereoscopic image. A retro-reflective marker worn by the observer removes the need for the observer to wear special viewing devices, whilst providing an infrared imaging system with a way to locate the observer's head. Image content may be driven by the observer's viewpoint. The two perspectives may be presented simultaneously using conventional display elements. A tapered lenticular structure provides a way to adapt to changes in the observer's distance from the display. Alternatively, each perspective image may be rapidly sequenced, either as two complete single images, or a sequence of suitably arranged compositions of the two. The infrared source used in the head tracking apparatus is modulated to aid image processing. The modulated source may also be used to synchronize a stereoscopic viewing device, switching views on a field sequential basis. Inter alia, the invention has applications in minimally invasive surgery, remote handling, virtual reality, teleconferencing and computer aided design and visualization.

    Abstract: Systems and methods for producing the sensation of 3-dimensional viewing are disclosed. Apparent 3-dimensional images are produced by simultaneously projecting at least two related images onto at least two associated projection screens, creating planes of images with each image plane having its own depth characteristic. Then at least two images are reflected or transmitted simultaneously by ghost glass to viewers who observe a composite image. The composite image provides viewers with the illusion of depth in the form of an apparent 3-dimensional image.
