Abstract

See full text

An imager defines a field of view and an optical axis. An illuminator directs illumination towards a region of interest, the region of interest being an intended position of the object. A tapered translucent diffuser is concentrically aligned with the optical axis, and has a first distal end proximate to the imager, and a second distal end proximate to the region of interest. The tapered translucent diffuser includes a darkened region, the darkened region to absorb a portion of the illumination to substantially reduce reflection of the portion of the illumination toward the object. A light guide can be positioned proximate the first distal end and the imager, such that a second illuminator can generate an aimer beam that passes through the light guide to produce an aimer pattern on the object.
