An aircraft ice detection and de-icing system (10) is disclosed in which an aircraft (20) is positioned remotely from a laser beam generator (12), a beam of radiant energy (14) is reflected from a mirror (16) so that the beam (14) impinges upon an aircraft surface (18) and the mirror (16) moves the footprint (36) about the aircraft (20). The beam (14) has a wavelength that is preferentially reflected by the aircraft surface (18) and absorbed by ice, such that the beam (14) heats and removes ice from aircraft surfaces (18). A remote thermal monitoring system (22) may also be used to monitor temperatures along the surface (18) for detecting regions experiencing temperature rises at relatively increased rates as they are treated with the beam (14), thus indicating the presence of ice. A visible light beam (27) may also be used to track and indicate movement of the footprint (36) of the treating beam (14). |
