Abstract
The present invention provides a visual display system that comprises an image generator and a plurality of adjacent video display modules. The image generator may be adapted to generate a video image viewable by an operator of the visual display system, where the video image may be representative of a portion of a composite display image. The plurality of adjacent video display modules include displays that may be adapted to display the portion of the composite display image, where the video display may be remotely coupled to the image generator and may be responsive to the video image generated by the image generator. The video display modules further comprise a plurality of holographic analogs of collimating mirrors (hereinafter called holographic collimators), each of the holographic collimators associated with each of the modules and positioned between the operator and the video display, where each of the holographic collimators allows the operator to view a portion of a display area of the video display module with a degree of head motion. The holographic collimators associated with adjacent modules are joined together along their edges and positioned to tessellate a sphere partially surrounding the operator, thereby permitting the operator to view the composite display image displayed on the plurality of video display modules through the plurality of holographic collimators and perceive the composite display image as a continuous far-focused virtual image, and wherein the distance of the video image displayed by the video display may be located at substantially half of an effective radius of a holographic analog of the collimating mirrors.
