REAR PROJECTION FACETTED DOME

A multi-facetted dome imaging system (10) utilizes rear projection imaging techniques to present a moving or still image to each screen facet (12). The trapezoidal facets (12) are arranged with a series of lower facets (16), upper facets (18), and a top facet (20) generally forming a dome (11). Each...

Zusammenfassung:	A multi-facetted dome imaging system (10) utilizes rear projection imaging techniques to present a moving or still image to each screen facet (12). The trapezoidal facets (12) are arranged with a series of lower facets (16), upper facets (18), and a top facet (20) generally forming a dome (11). Each facet (12) has a projector (30) disposed at its rear to project the image. Visibility of facet joints is minimized by joining the facets (12) by a pair of transparent stiffeners (42, 44) which hold the mating portions of the screen facets (12). The stiffeners (42, 44) are suspended by springs (48), which are held by a support structure (50).
