Paper Abstract

Brightness, resolution and color required of simulation visuals challenge the display state of the art. The recently emerged liquid crystal light valve technology has the potential for high brightness and resolution and, by virtue of its modularity, can be implemented in a variety of configurations to meet specific requirements. The basic building blocks of the projector are the display channel (including the light valve), illumination system, polarizing prism and the projection optics. Each is described and their range of performance characteristics is indicated. Two examples of possible projector configurations are given to illustrate the modularity and flexibility of the technology: a medium resolution full-color back-ground projector, and a higher resolution color background projector with the capability of displaying high resolution monochrome targets inset into the main raster. Finally, the paper discusses features of liquid crystal light valve projectors which are particularly attractive for simulation applications: flexibility in display formats, high resolution, polarized light output, telecentric projection optics and modularity.
