Multiple Projector Small Dome Display

摘要

This document describes the Multiple Projector Small Dome Display Project. Thegoal of this project was to demonstrate the capability of current low-cost liquid crystal display projectors to create a low-cost dome display system. Four such projectors were configured to project on a 10-ft-diameter half-dome. The ability of the image generator to pre-correct the image for the distortion of the curved projection surface was essential since the projectors offered no raster adjustments. As configured for this project, the four projectors provided a field of view of 70 degrees horizontal by 45 degrees vertical. Performance of the display provided better than 6 arc minutes per pixel resolution, brightness of 4 foot-lamberts and a contrast ratio of 28 to 1....Aspect ratio, Distortion correction, Low cost dome display, Brightness blending, Field of view, Viewer attitude, Design eyepoint, Liquid crystal display projectors, Window definitions.
