RA981004 HOLOGRAPHIC SCANNER DISC WITH DIFFERENT FACET AREAS Abstract A scan pattern for a bar code scanner is pro- duced by the combination of a coherent light source, a rotating disc with holographic facets and an array of fixed, beam folding mirrors. Light reflected from a bar code label follows a retro- reflective path to a photodetector within the scanner, To reduce variations in the amount of light collected through different facets, the areas of the facets are varied as a function of beam elevation and beam path length.
