Anwar S Khattak: High resolution laser beam scanner and method for operation thereof. Wells St John Roberts Gregory & Matkin, July 13, 1993: US05227910 (23 worldwide citation)

A laser beam scanner in its preferred form has a laser source which emits a laser beam at a prism. The prism receives and deflects the laser beam toward a spherical lens, which receives the laser beam and converges it. A spherical reflector then redirects and focuses the converging laser beam to a l ...
