An optical triangulation tracking system comprises means for creating at least two beams of light (14, 15), each being divergent, mounted relative to one another in a predetermined spatial and angular relationship such that the beams intersect one another thereby illuminating a volume of space (16), at least one reflector (3) relatively moveable within said volume of space, a light detection device (20) adapted to receive light from each of the two beams which has been reflected back along its path of transmission by the reflector and an image processing system (24, 25) connected to each of said detection devices, the arrangement being such that relative movement between said light beam creation means and the reflector will be monitored by the image processing system which determines from received images by triangulation spatial coordinates of the reflector thereby to determine the relative position within said volume of space of the reflector. |
