Abstract
The invention provides line scanning and frame scanning apparatus for the projection of images, particularly for head-coupled area-of-interest visual display apparatus for ground-based flight simulators. The line scan apparatus is cockpit-mounted and comprises a modulated laser beam which is scanned over a line of fibre optic guides forming a ribbon by which the line image is transmitted to a helmet-mounted frame scanner. A sensor measures head/helmet movement to permit voluntary scanning of a wide angle of simulated view from the craft. The invention permits of lightweight helmet-mounted equipment for this purpose.
