Fold mirrors permit the imagers to be closer to each other and permit an optical code reader, such as a tunnel scanner, to confine them to a smaller housing volume or capacity. A plurality of sets of fold mirrors can also be employed to convey at least a portion of at least two different perspectives or two different depths of field of a composite view volume to different regions of an image field of a common imager. The sets of fold mirrors may also include split mirrors that have mirror components that reflect images from different view volumes to different imagers or different regions of an image field of a single imager.
