Abstract (en)
[origin: CA2345124A1] An optical head assembly, method and procedure which generates and then precisely positions multiple light beams (201) onto a target. The system diffracts an input light source into a multiple light beam (215) pattern, or initially generates a multiple light beam pattern, in which individual beams of the multiple light beam (215) pattern are precisely spaced, corrected, focused and directed through a two axis plane (222, 223) to the target with minimal movement of any components of the optical head assembly. Such individual beams can also be individually modulated.
