ABSTRACT:
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, projected onto the inside of a part-spherical shell which carries a concave retro-reflective screen and surrounds the pilot. The displayed scene covers an area of interest centered upon the pilot's line of view. The image generator used may be of the computer generated image, laser-scanned model or closed-circuit television type. For the pseudo-collimated display, the same image is projected for left and right eyes from points on a pilot's helmet above the pilot's eye positions. Line scan apparatus is mounted in the pilot cockpit. Line image transmission is by fibre-optic light guide ribbon and two such light guide ribbons are used to restrict impairment of the image by fibre fracture. Common frame scan apparatus is mounted on the pilot's helmet. A sensor measures the pilot's head/helmet movement to permit voluntary scanning of a wide angle of simulated pilot view from the craft.
