| 英文摘要 | PURPOSE:To easily modulate the strength of an optical beam by providing plural semiconductor laser light sources, a drive circuit capable of individually turning on and off these light sources and an image forming optical system matching light beams from the plural laser beams. CONSTITUTION:Semiconductor laser 11a, 11b...11n are individually turned on and off respectively by drive circuits 12a, 12b...12n. The light beams Ra, Rb...Rn from the respective semiconductor lasers 11a, 11b-11n are transmitted or reflected by half mirrors of half prisms Ma, Mb-Mn of image forming systems and matched to one light Ro. The finally matched light beam Ro scans a recording surface or a display surface through a deflecting system. In this case, the modulation of the strength of the light beam is carried out for instance by turning on the laser 11a, and turning off the other and the modulating strength can be changed by changing a set value of a current of the respective semiconductor lasers. |
