ABSTRACT:
An integrated optical imaging assembly for scanning an object may comprise a printed circuit board having an upper end and a lower end. An optical detector is mounted to the upper end of the printed circuit board at an end of an image light path, and a lens system is mounted to the printed circuit board below the optical detector to be interposed in the image light path. A reflector is mounted to the lens in the image light path between the lens and the optical detector to direct the image light path between the lens and the optical detector. An illumination source is mounted to the lower end of the circuit board to illuminate a second end of the image light path below the lens, and an illumination reflector is mounted to the lens opposite the illumination source to direct an illumination light path from the illumination source toward the image light path below the lens.
