Abstract
A method and apparatus to permit digital capture of images from both transmissive and reflective media. A laser or other source of excitation radiation is coupled to a mounting surface to be in optical communication with a reading window when installed on a scanner. A rear casing is coupled to the monitoring surface to engage a housing of a scanner, the housing defining the reading window.
Claims9
A method comprising:
- selecting between a transmissive scan mode (TSM) and a reflective scan mode (RSM);
- backlighting a transmissive medium if TSM is selected;
- and
- generating a scan pattern if RSM is selected.

A method comprising:
- simultaneously backlighting a medium and exposing the medium to an excitation radiation;
- capturing an image generated by a release of energy responsive to the excitation radiation if the medium is reflective;
- and
- capturing an image exposed by the backlighting if the medium is transmissive.
