Filed:

Oct 24, 2001

Appl. No.:

10/000945

Inventors:

Donald C. Conemac - Simi Valley CA, US
Eric Harlen Ford - La Canada CA, US

Assignee:

Advanced Laser Technologies, Inc. - Camarillo CA

International Classification:

G09G 300

US Classification:

345 32, 345108, 345110, 359204, 359216

Abstract:

A light beam display employing interlaced light beam scanning comprising a display screen having a vertical and a horizontal dimension, a source of a plurality of light beams and an optical path including a movable reflector having a plurality of reflective facets between the display screen and the light beam source. The movable reflector directs the plural light beams to the display screen via one or more facets of the movable reflector to simultaneously illuminate plural different scan lines of the display which are spaced apart by plural non-illuminated scan lines. An optical mechanical element is provided for vertically shifting the light beams so as to illuminate different scan lines of the display screen.

Inventors:

Eric Ford - La Canada CA, US

International Classification:

H04N003/08

US Classification:

348/203000

Abstract:

A light beam display employs a polygon reflector to scan one or more light beams in horizontal scan lines on a display screen. A horizontal scan line correction lens is provided in the optical path between the display screen and the polygon reflector to correct scan line bowing. An optical mechanical element is provided for vertically shifting the light beams so as to illuminate different scan lines of the display screen. Control electronics is employed to adjust the timing on a line by line basis to correct vertical pixel line distortion introduced by the correction lens.

Abstract:

A head up display or HUD system, including methods and apparatus, suitable for use in a flight simulator. According to the present teachings, a flight simulator HUD may be configured to produce a HUD image that appears superimposed on a simulated cockpit field of view image, and which has substantially the same relatively short focal distance from the user as the simulated image. A simulator HUD according to the present teachings does not require any holographic optical elements or an unrealistic cockpit volume, and provides an accurate simulation of conditions in a real aircraft cockpit.
