Application: Ablation tool (Patent ID: US20230400665A1)

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 a borescope or flexible robot arm, with the laser source located externally and connected to the tool using an optical fiber. The mirror is set at a specific angle, and after the laser beam reflects off the mirror, it passes through a lens. The tool also includes mechanisms for both rotational and directional movement of the mirror, with options for different types of mirrors and rotation mechanisms.

The method described in the patent involves coupling the laser to the ablation tool, positioning the tool near the area to be ablated, starting the laser and initiating the rotation of the prism, and using the mirror to scan the laser beam across the target area. The patent also includes a computer program for performing this method. Overall, the patent outlines a laser ablation tool with specific components and functionalities for precise and controlled ablation of components, with detailed mechanisms for movement and rotation, as well as a method and computer program for utilizing the tool effectively.
