Claim 7:
8. An apparatus of an optical scanner for scanning a subject, the apparatus comprising:
interface circuitry including an input to receive an at least one image from at least one image-capture device of the optical scanner; and
controller circuitry coupled to the interface circuitry and the input, the controller circuitry operative to process the at least one image to determine ranging between the optical scanner and the subject based on (a) projection of a pair of divergent aimer beams projected by an aimer transmitter system of the optical scanner to produce a corresponding pair of reflections off of a surface of the subject, and (b) detection of a position of at least one aimer-beam reflection of the pair of aimer-beam reflections within the at least one image;
wherein the pair of divergent aimer beams are divergent such that the pair of reflections, as captured in the at least one image by the at least one image sensor, are separated from one another by the same separation distance within each captured image, regardless of the ranging;
wherein any change in the separation distance is indicative of an occurrence of an optical misalignment of the optical scanner;
wherein each reflection off of the surface of the subject comprises an aimer pattern; and
wherein an indicator of the distance between the surface of the subject and the at least one image-capture device of the optical scanner includes a distance between a centerline of the at least one imager and a midpoint position of the aimer pattern.
