Classification: CPC G | IPC G

Claim 7:
8. An on-axis aimer and distance measurement apparatus for a vision system comprising:
a light source configured to generate a first light beam along a first axis, the first light beam configured to project an aimer pattern on an object;
a reflecting assembly configured to direct the first light beam received from the light source to be projected onto the object along a second axis and configured to receive reflected light from the first light beam on the object along the second axis, and to direct the reflected light from the second axis to a third axis;
a receiver configured to receive the reflected light along the third axis to determine a distance between a lens of the vision system and the object; and
a processor device configured to control one or more parameters of the vision system for acquisition of an image of the object based on the determined distance;
wherein the reflecting assembly comprises at least two elements and wherein at least one of the at least two elements directs the first light beam received from the light source so that the first light beam is projected onto the object along the second axis coaxially with a reader optical axis and at least one of the at least two elements receives the reflected light along the second axis and directs the reflected light from the second axis to the third axis.
