Abstract

Laser-scanning techniques are important in the decomposition of images to digital data and the reconstruction from digital to hard-copy output. Laser scanning has been applied to a variety of information processing needs, ranging from microfiche applications,¹ platemaking and facsimile,^2,3 to high-speed xerographic printers.⁴ The input signal is typically derived from a laser-scanned photosensor array or from a purely electrical source such as a computer driven character generator. The original document is reconstructed at the output terminal by interaction of a scanned-laser beam with a photoreceptor surface.
