Claim One:
1. An improved apparatus for visual simulation utilizing a domed retroreflective screen, a dual channel computer image generator, with one channel dedicated to a high resolution area of interest and a second channel dedicated to a lower resolution instantaneous field of view, a laser modulation and line scanning system for outputting a plurality of laser line scans in accordance with said computer image generator channels, a plurality of flexible coherent fiber optic bundles for transmitting said line scans, a projector housing operably connected to said fiber optic bundle, and a helmet to be worn on an observer's head adapted for mounting said housing thereon, wherein said improvement comprises: an optical system mounted within said projector housing comprising, means for generating frame scan for each projected laser line scan, connected to receive transmission from said laser modulation and line scanning system via said fiber bundles, said generating means including means for combining said laser line scans in a single projected frame such that a projected image is formed having a high resolution area of interest bounded by a lower resolution instantaneous field of view; means for controlling said scan generating means operably connected to receive control signals from said computer image generator; and means for projecting said laser raster through a wide angle onto said domed screen operably positioned to receive said raster from said scan generating means.
