Abstract: A holographic laser scanner for producing a high-resolution raster-type 2-D laser scanning pattern within a 3-D scanning volume. The scanner comprises a housing, holographic laser scanning mechanism disposed within the housing for producing a high-resolution raster-type 2-D scanning pattern within a 3-D scanning volume. The holographic laser scanning mechanism includes a laser beam source for producing a laser beam, and a holographic scanning disc rotatable about an axis of rotation and supporting a plurality of holographic optical elements. The laser beam is directed towards the holographic laser scanning disc at an angle of incidence so that the laser beam is diffracted by the holographic optical elements and produce a raster-type 2-D laser scanning pattern for scanning code symbols within the 3-D scanning volume.
