ABSTRACT:
A device for tracking an object (12) in three dimensional space is provided which comprises a fiber optic sensor array (14). Fiber optic sensor array (14) comprises a row plane (16) and a column plane (18) each comprising a plurality of parallel optical fibers bonded together. A row detector (20) is coupled to the ends of the fibers comprising row plane (16). A column detector (22) is coupled to the ends of the fibers comprising column plane (18). Row and column detectors (20) and (22) are coupled to a decoder circuit (24). First and second beam generators (26) and (28) are affixed to the object (12) and are each operable to transmit beams (30) and (32) which terminate on the fiber optic sensor array (14). By determining the points of incidence of beams (30) and (32), the decoder circuit (24) may determine the position of the object (12) in three dimensional space.
