Abstract
An apparatus and method for controlling the temperature profile of the surface of a medium such as a solid or a liquid. The surface is imaged onto an array of detectors which generate an electronic output indicative of the temperature profile of the surface. A heating beam provided by a laser is scanned across the surface, providing radiation which heats the surface locally in a pattern based upon the detected temperature profile and the desired temperature profile.
