ABSTRACT:
An apparatus and system for determining the angular orientation of an object comprised of a light source directing an optically detectable beam of light at an orientation dependent reflector coupled to an object whereupon a light sensor positioned adjacent the light source detects the reflected optically detectable beam of light from the orientation dependent reflector and determines the centroid of reflection thereon from which the angular orientation of an object throughout a range of rotation about at least one axis of rotation is obtained.
