Abstract

A light-scanner (200) that includes a wave guide (230). The scanner (200) defines a scanning zone, and further includes a light-emitting diode (214), and a detector. The wave guide (230) is disposed between the light-emitting diode (214) and the scanning zone. The wave guide (230) defines a light-admitting aperture and a light-reflective surface. The light-admitting aperture and light-reflecting surface cooperate to direct light from the light-emitting diode toward the scanning zone, and to focus such light centrally along a path traveled by such light toward the detector.
