Abstract:
1. A compact imaging module for an imaging reader, comprising: an imaging assembly including a solid-state imaging sensor, and an imaging lens system for capturing return light from a target to be imaged over an imaging field of view of the imaging sensor, and for projecting the captured return light onto the imaging sensor; an aiming light assembly including an aiming laser for emitting an aiming beam, and a lightpipe for optically modifying the aiming beam to generate and shape an aiming light pattern on the target, the lightpipe having an entry surface through which the aiming beam enters the lightpipe, an exit surface through which the aiming beam exits the lightpipe, and a pair of total internal reflecting surfaces between the entry and exit surfaces for twice folding the aiming beam to pass through the lightpipe along a double-folded path to form the aiming light pattern that at least partly overlaps the imaging field of view, wherein the entry surface and the exit surface are parallel to each other; and a support assembly for spatially adjusting the aiming light pattern relative to the imaging field of view.
