Note: the patents described as laser sensitometer provide the dual description of an industrial laser printer. In them, laser beams are used to write on photo sensitive imaging materials. US Patent 6903824 refers to a multiple-wavelength high-speed industrial laser system that exposes imaging materials in the nanosecond regime. All these patents have been reduced to practice.
