Abstract: Special features of a new 523-line scanned laser display system are described. These include: (1) the addition of beam wobbling to the polygonal mirror scanning system to allow improvement of the horizontal resolution by a factor of 3.6; (2) a relay lens between the horizontal and vertical deflectors, to minimize deflector aperture requirements; (3) an auxiliary deflection system to compensate for raster irregularity; and (4) an automatic optical black-level control system. The resulting horizontal and vertical resolutions are 500 and 370 TV lines, respectively, and raster uniformity is excellent. Horizontal jitter is less than 0.02 μs and vertical jitter is unnoticeable. The primary colors used and their sources are: 632.8 nm (He–Ne laser), 514.5 nm (argon ion laser) and 476.5 nm (argon ion laser). Low screen brightness is the biggest remaining problem.
