    Abstract: A laser scanning apparatus raster scans an input laser beam ( 0) by using an acousto-optic deflector arrangement. The laser beam is horizontally scanned by a pair of acousto-optic deflectors (13a, 13b). Thus, a laser scanning apparatus can be realised which is low in noise, of excellent durability, small in size, light in weight and which can display a picture of high quality at high speed.

    Abstract: A laser scanning apparatus (A1) having horizontal and vertical deflection means (7; 13) for deflecting n laser beams of the same wavelength modulated by n kinds of pattern information signal components in the horizontal and vertical directions. The n laser beams ( l 1, l 2, l 3) are spatially separated so that the pattern information is directly drawn on a plurality of drawn media. Thus, pattern information of different patterns can be drawn on the plurality of drawn media by one horizontal deflection means (7) and one vertical deflection means (13), whereby the laser scanning apparatus (A1) can be made compact in size, light in weight and small in power consumption. Also, the pattern information can be drawn with high coupling ratio (high light utilizing ratio and proper brightness) and high resolution.
