<p>Methods and apparatus for determining the angular orientation of an object are disclosed. In one embodiment, an orientation detection system according to the invention includes a light source directing an optically detectable beam of light at an orientation dependent reflector coupled to an object. The light sensor is positioned adjacent to the light source and detects the reflected optically detectable beam of light from the orientation dependent reflector, thereby determining the centroid of reflection thereon, from which the angular orientation of an object throughout a range of rotation about one or more axes of rotation is obtained.</p> |
