Methods, systems, and apparatuses for scanning and decoding direct part marking indicia

A method for scanning and decoding direct part marking (DPM) indicia, the method comprising:

• receiving, by a beam splitter, an illumination projected from an illumination source;
• projecting, by the beam splitter, the illumination as an in-line illumination wherein the in-line illumination includes light rays directed along a first direction of a target, wherein the target comprises a DPM indicia;
• directing, by a telecentric lens, a first portion of reflected light from at least one rough surface of the target that is incident on a second surface of the telecentric lens in a direction away from an imager;
• exposing the imager to a second portion of reflected light from the target that is directed by the telecentric lens in a second direction of the imager, wherein the second portion of reflected light is directed in the second direction along an imaging axis of the imager;
• and
• capturing, by the imager, an image of the DPM indicia based on the second portion of reflected light.
