Abstract
An aircraft ice detection and de-icing system is disclosed in which an aircraft is positioned remotely from a laser beam generator, a beam of radiant energy is reflected from a mirror so that the beam impinges upon and creates a footprint upon a surface of the aircraft and the mirror is manipulated to move the footprint about the aircraft surface. The beam has a wavelength that is preferentially reflected by the aircraft surface and absorbed by ice, snow and water, so the beam heats and removes ice, snow and water from aircraft surfaces as the beam's footprint is moved thereabouts. A remote thermal monitoring system may also be used to monitor temperatures at the aircraft surface for detecting regions experiencing temperature rises at relatively increased rates as the regions are treated with the beam, thereby indicating the presence of ice, snow or water. A visible light may also be used simultaneously to track and indicate movement of the footprint of the treating beam about the aircraft surface.
