Abstract
The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators. The apparatus provides a display projected onto the inside of a part-spherical shell which surrounds the pilot and carries a retro-reflective screen. The displayed scene covers an area of interest dependent upon craft position and heading and viewer's instantaneous line of view. The image generator may be of the computer generated image, laser-scanned model or closed-circuit television type. Multiple images are required for stereoscopic viewing or for more than one viewer. Line scanning apparatus is cockpit-mounted; line image is transmitted by fibre optic light guide ribbon and frame scan apparatus is mounted on a helmet worn by the viewer. A sensor measures head/helmet movement to permit voluntary scanning of a wide angle simulated view from the craft. The projected image is divided into zones each zone using separate line-scanning means and fibre optic light guide. The frame scanning projector means provides simultaneous frame scanning of each zone.
