Abstract
A raster output scanner having a recording member, a laser, a total internal reflection type modulator having an array of independently addressable electrodes, optical means cooperable with the laser to provide a sheetlike beam of high intensity radiation at the modulator, the array of electrodes being pulsed in succession with each image pixel to provide wave after wave of imaging or non-imaging beams, a scanning polygon for scanning the imaging beams from the modulator across the recording member line by line, and means for pulsing the modulator electrodes at a speed equal to the speed of the scanning polygon and in a direction opposite to the polygon scanning direction to obviate image blur.
