ABSTRACT:
In a laser scanner of the type having beam shaping means and a stationary diffraction grating for directing the shaped beam to a hologon scanning disc, the beam shaping means is combined with the stationary diffraction grating by providing a shaped stationary diffraction grating, thereby eliminating the need for other beam shaping means prior to the shaped diffraction grating, thereby simplifying construction of the apparatus.
