Abstract: A system for providing six-dimensional position data of an object in a three-dimensional (3D) space, the system including a light source configured to emit a light beam in an x-direction, a mirror including a mirror plane disposed in an x-y plane and a beam splitter configured for reflecting the light beam from the light source onto the mirror before being directed to the object, the light beam reflected by the object onto the beam splitter before being directed through a lens to an image plane to form an image.

Abstract: An optical system including an enclosure including a front end and a rear end, a first pair of apertures configured to be disposed on a front plane on the front end of the enclosure and a single optical lens system disposed between the front end and the rear end of the enclosure, wherein the first pair of apertures are configured to allow sets of light rays into the enclosure through the single optical lens system to be cast on an image plane as first and second spots, the image plane being parallel to the front plane, if the first and second spots are concentrically disposed, the sets of light rays are determined to be parallelly disposed with respect to one another, otherwise the sets of light rays are determined to not be parallelly disposed with one another.
