HEAD UP DISPLAYS FOR MOTOR VEHICLES

Improvements in or relating to visual display apparatus

The invention provides head- coupled area-of-interest visual display apparatus particularly for ground- based craft-flight simulators. The apparatus provides binocular, pseudo- collimated vision of a display for both pilot and co-pilot projected onto the inside of a part-spherical shell, which carries a concave retro-reflective screen and surrounds the two pilots. The displayed scene covers an area of interest centred upon each pilot's line of view. A separate image generator is used for each pilot and may be of the computer generated image, laser- scanned model or closed-circuit television type. For the pseudo- collimated viewing, the same image is projected for left and right eyes for each pilot from points on a respective pilot helmet, above the pilot's eye position. Line scan apparatus is mounted in the pilots' cockpit; line image transmission is by fibre optic light guide ribbons; and frame scan apparatus is mounted on the two pilots' helmets. Sensing means detect head/helmet movements ...
