ABSTRACT:
A device for electro-optical monitoring of angular and lateral deflections of a moving carriage relative to a stationary track along which it moves, including a transmitting unit mounted on the moving carriage and including a light source illuminating a pattern, a receiving unit mounted on the track in light receiving relationship with the transmitting unit and including optical sensor apparatus for sensing the light transmitted from the transmitting unit and providing an output signal corresponding thereto, and a micro computer arranged to receive the output signal from the receiving unit and to determine the angular and lateral deflection of the carriage utilizing the information derived from the signal.
