ABSTRACT:
An array of light sources transmit a series of light beams onto an object and the reflected light beams are focussed on a light responsive transducer. The output signals of the transducer are processed to determine the location and orientation of the object. The location and orientation information in turn is available to control the operation of a tool or manipulator relative to the object.
