Title: Raster output scanner
Inventor: AMATSUIA FUAINBAAGU
IPC: H04N1/113
Filed: 1993-04-14
Abstract: PURPOSE: To reduce intensity changes on a scan line of modulated light beams by adjusting the attenuation of the modulated light beams in each area of each scan line by using the characteristic of a liquid crystal window. CONSTITUTION: An acousto-optical modulator 20 modulates light beams 14 that are emitted from a light source 12 and forms modulated light beams 21. The beams 21 are directed towards a rotating polygon 26, and the polygon 26 linearly scans the beams 21 on a liquid crystal output window 30. The window 30 covers light beam scan over one scan line and generates light beams, that have uniform intensity by each cell that corresponds to each part of an attenuation curve 50 from cells 54 and 60, which have zero attenuation and cells 56 and 58 which have the maximum attenuation. Thus, even the modulator 20, whose intensity fluctuations are large, can be used for a raster output scanner 10, and also the uniformity of a printed image can be improved by correcting nonuniformity of the beams 21 with the window 30.
