摘要:
一种光扫描装置,通过在印相纸等感光材料上扫描按照图像信息所调制的各色激光进行曝光,并且不发生由于应照射在相同的位置上各色激光的偏移而发生的偏移。红色LD和绿色SHG激光元件及蓝色SHG激光元件的各光源发出的各色光束,按照图像信息由AOM进行调制。然后,对于驱动这些AOM的AOM驱动器15R、15G及15B分别通过时钟频率控制部25控制其曝光扫描时钟。
摘要(英):
An optical scanning device which performs an exposing operation with respect to a photosensitive material such as a printing sheet, etc., by scanning with laser beams in respective colors modulated according to image data is arranged so as to modulate light beams in respective colors projected from respective light sources of a red LD, a green-color SHG laser unit and a blue-color SHG laser unit by AOMs according to image data. Then, the clock frequency control section adjusts an exposure scanning clock for each of the AOM drivers for driving these AOMs individually. It is therefore possible to suppress an aberration in color caused by a shift in light beams in respective colors which are to be projected onto the same target position.
