ABSTRACT:
A method and an apparatus is provided for reducing the effects of laser noise and for improving modulation transfer function in scanning a surface of a photoconductive plate with a spot of light through use of a time-light intensity integration method. The method comprises pulse synchronization or infrared synchronization to control activation and deactivation of signal detection laser light beams.
