Optical image bars are arrays of light emitting pixels or arrays of pixel-sized shutters controlling the light output of a uniform source. A typical image bar is a page-wide single or double line array electrically addressed "line at a time". The arrays are used to imagewise expose a photosensitive medium such as a charged photoreceptor, which moves orthogonally to the image bar. Examples of image bars are liquid crystals (light controlling) and LED'S (light emitting).
