    摘要： A laser-based method of removing a coating from a surface comprises directing a laser pulse to a first position on the surface, removing the coating from the first position by rapidly elevating a surface temperature of the first position using the laser pulse and thereby disassociating the coating from the surface and collecting the disassociated coating. In some embodiments, the coating comprises an environmentally harmful substance such as Hexavalent Chromium. In some embodiments, the coating comprises Diamond-Like Carbon (DLC), Vitrified Contaminant Material (CMAS). The disassociated coating is collected by a waste collector.

    摘要： A coating removal apparatus removes a coating from a surface. The apparatus has a movable scanning head and scanning optics. The scanning head is movable in one dimension, and the scanning optics adjust in two dimensions to compensate for movement of the scanning head to implement long range scanning with a uniform scanning pattern. Further, a surface roughness is determined by measuring specular and scattered reflections at various angles. For composite surfaces, the apparatus utilizes UV laser radiation and a controlled atmosphere to remove coating and alter the chemical characteristics at the surface.

    摘要： A coating removal apparatus utilizing a common optics path to provide laser pulses to a coated surface and to direct a light illumination reflected from the coated surface to a photosensitive detector and analyzer. The apparatus is an integrated device including a laser source, a beam splitter, scanning optics, a waste removal apparatus, one or more light illuminators, a photosensitive detector, a comparator, and a control logic circuit. Alternatively, the laser source is external to the integrated device and a fiber optic cable is used to connect the laser source to the integrated device.

    摘要： A rotary refractive laser scanner head uses two sets of lenses and prisms aligned along a common optical axis. Each prism is paired with one of the lenses. The lens-prism pairs are separately mounted rotatable on a common axis coaxial with the optical axis. A motor drives two gear sets. Each gear set is separately coupled to one of the two lens-prism pairs and rotates them at selected, typically different speeds. An input laser beam is directed along the optical axis at one of the lens-prism pairs. The first pair collimates and refracts the input beam into an intermediate deflected beam according to Snell's law and the characteristics of the laser beam and optics. The second pair receives the intermediate beam and further deflects it to form an output beam. By selecting the motor speed, gear ratios, optics spacing, characteristics and prism wedge (deflection) angle, the scanner head effectively can scan an output laser beam over a desired pattern area.

    摘要： A coating removal apparatus utilizing a common optics path to provide laser pulses and light illumination to a coated surface. Reflected light resulting from the light illumination impinging the coated surface is directed to a photosensitive detector and analyzer. The reflected light is either sensed directly from the coated surface by the photosensitive detector or the reflected light is directed along at least a portion of the common optics path to the photosensitive detector. The apparatus is an integrated device including a laser source, a beam splitter, scanning optics, a waste removal apparatus, one or more light illuminators, a photosensitive detector, a comparator, and a control logic circuit. Alternatively, the coating removal apparatus is configured as a head component coupled to a body component.
