Abstract
PURPOSE: To control light deflection quantity and correct deflection distortion and intensity distortion of scanning light beam by applying the light deflection distortion correcting signal produced by the vatiation at the deflecting point of a rotary polyhedral morror to a correcting light deflector provided in the incudent optical path of the light beam.
