Aiming light patterns for use with barcode readers and devices systems and methods associated therewith

An imaging engine comprising:

• a first imaging assembly having a first field of view (FOV), the first imaging assembly configured capture image data over a first working distance range extending between a first far-working distance (FWD1) and a second far-working distance (FWD2), the FWD1 being closer to the first imaging assembly than the FWD2;
• a second imaging assembly having a second FOV, the second imaging assembly configured to capture image data over a second working distance range extending between a first near-working distance (NWD1) and a second near-working distance (NWD2), the NWD1 being closer to the second imaging assembly than the NWD2, the first working distance extending further than the second working distance range;
• and
• an aiming assembly configured to emit an aiming light pattern, the aiming light pattern including a first portion and a second portion, the second portion having a first sub-portion and a second sub-portion separated from the first sub-portion by a space,
• wherein the aiming assembly is configured such that when the aiming light pattern is projected on a working surface positioned between the NWD2 and the FWD2, each of the first sub-portion and the second sub-portion is outside of the first FOV.
