A method and apparatus for detecting for detecting an object within a radiating beam of a radiating source. The method receives reflected and radiated radiation directly from the object to provide a radiation signal. The method then processes the radiation signal to provide a control to the radiating source. A concomitant apparatus comprising a detector and a control circuit is provided. The detector receives reflected and radiated radiation directly from the object and provides a radiation signal indicative of the reflected and radiated radiation received from the object. The control circuit, coupled to the detector, processes the provided radiation signal to provide a control signal to the radiating source.
