Title: Beam pattern contractor and focus element, method and apparatus

Abstract: An optical head assembly, method, and procedure which generates and then precisely positions multiple light beams onto a target. The system diffracts an input light source into a multiple light beam pattern, or initially generates a multiple light beam pattern, in which individual beams of the multiple light beam pattern are precisely spaced, corrected, focused and directed through a two axis plane to the target with minimal movement of any components of the optical head assembly. Such individual beams can also be individually modulated.
