摘要： A light scanning device comprising a source of a parallel light beam. The parallel light beam is passed through a first liquid crystal shutter and a first lens to converge at a focal point thereof. A rectangular light reflecting box with inside reflecting surfaces is arranged next to the first lens, so that a portion of the light beam passing through the first lens is able to directly pass through the light reflecting box and another portion of the light beam is reflected at the reflecting surfaces and then able to pass through light reflecting box, whereby multiple light paths are obtained. The passage of the multiple light paths is controlled by a second liquid crystal shutter located on the end of the rectangular light reflecting box, the second liquid crystal shutter having a plurality of selectively controllable light permeable regions. The light beam is finally impinged on a desired light recording media, and thus it is possible to scan the light recording media by controlling the second liquid crystal shutter to allow a portion of light beam of a selected light path to form a spot of light on the media.
