Monolithic mirror structure for use in a multi-perspective optical code reader

摘要

A monolithic compound mirror structure is used in an optical code reader employing an imager that captures images of items bearing optical codes in a viewing volume of the optical code reader. The monolithic compound mirror structure comprises a plurality of highly reflective surfaces positioned on the structure so that the structure can be positioned in a field of view of the imager in the optical code reader and oriented so that two or more of the plurality of highly reflective surfaces appear in the field of view of the imager, to thereby split the field of view of the imager into two or more different views into the viewing volume. The different views into the viewing volume may be direct off of the monolithic compound mirror structure or indirect off of one or more intermediate mirrors.
