Abstract
A non-contacting sensing system for measuring dimensions or determining the position of an object, such as a workpiece in an automated machining process. A small diameter light beam is projected and focused at a predetermined location. A television camera, positioned to view the location, receives light reflected from the location and generates a video signal. This signal is provided to a circuit which detects changes in signal magnitude indicative of a change in position of the object relative to the predetermined location.
