The patent filed by Rolls-Royce Holdings Plc describes a laser ablation tool that includes a pulsed laser source, a rotating prism, and a movable mirror set at an angle relative to the laser source. The tool is mounted within a housing that can be coupled to the end of a borescope or flexible robot arm, with the laser source located externally and connected to the tool using an optical fiber.
The tool's mirror is set at a specific angle, and after the laser beam reflects off the mirror, it passes through a lens. The mirror is capable of both linear and rotational movement, and can be a concave or spherical mirror. The rotation mechanism for the prism can be driven by a motor, pneumatic turbine, or piezoelectric drive, with encoders ensuring accurate positioning. The method of ablating a component using this tool involves positioning the tool, starting the laser, initiating rotation of the prism, and moving the mirror to scan the laser beam across the target area. Additionally, a computer program is provided for performing this method.
