Abstract:
Various embodiments described herein relate to a scanning system for scanning and decoding direct part markings (DPM) type indicia. The scanning system includes an arrangement of an illumination module, a beam splitter module, and a telecentric lens assembly. The telecentric lens assembly is adapted to direct an in-line illumination received from the illumination module as collimated light to illuminate the DPM indicia. Upon illumination, a first portion of light reflected from embossments of the DPM indicia that are incident on the telecentric lens assembly at a defined angle is decoupled from an optical path between the telecentric lens assembly and the target. An imager is exposed to a second portion of reflected light, excluding the decoupled reflected light that is reflected from a substrate on the DPM indicia, in order to capture an image of the DPM indicia for decoding.

Claim (Index 9):
A scanning system adapted to be mechanically coupled to an optical reader, the scanning system comprising:\n an illumination module configured to provide an illumination; a beam splitter module configured to project the illumination as an in-line illumination with respect to an imaging axis of an imager of the optical reader, wherein the beam splitter module projects the in-line illumination in a first direction of a target including a Direct Part Markings (DPM) indicia; and a telecentric lens assembly configured to:\n direct the in-line illumination, incident on a first surface of the telecentric lens assembly as collimated light, in the first direction of the target parallel to an optical axis of the telecentric lens assembly; \n direct, a first portion of light reflected from at least one rough surface of the target that is incident on a second surface of the telecentric lens assembly, at a defined angle with respect to the optical axis of the telecentric lens assembly, wherein the first portion of the reflected light is directed in a direction away from the imager; and \n direct, a second portion of the reflected light from the target, that travels parallel to the optical axis of the telecentric lens assembly and is incident at the second surface of the telecentric lens assembly, in a second direction of the imager, wherein the second portion of the reflected light is received at the imager in order to capture an image of the target.
