    摘要： A surface treatment laser beam delivery and tracking system is provided. The laser generates laser light along a original beam path at an energy level suitable for treating (e.g., eroding) a surface. An optical translator shifts the original beam path onto a resulting beam path. An optical angle adjuster changes the angle of the resulting beam path relative to the original beam path such that the laser light is incident on, and spatially distributed, the surface to be treated. A motion sensor transmits light energy to the surface and receives reflected light energy from the surface via the optical angle adjuster. The light energy transmitted by the motion sensor travels on a path that is parallel to the shifted beam as they travel through the optical angle adjuster. The reflected light energy is used by the motion sensor to detect movement of the surface relative to the original beam path and generate error control signals indicative of the movement. The optical angle adjuster is responsive to the error control signals to change the angle of the resulting beam path and the angle of the motion sensor's light energy in correspondence with one another. In this way, the beam originating from the treatment laser and the light energy originating from the motion sensor track together with the surface movement.

    摘要： A method and system are provided for eroding or ablating a shaped volume of an eye's corneal tissue in accordance with the treatment of a specified eye condition. To determine the laser beam shot pattern, a plurality of laser beam shots of uniform intensity are first selected to form a uniform shot pattern of uniform shot density. The laser beam shots applied in accordance with the uniform shot pattern of uniform shot density would be capable of eroding a volume of the corneal tissue of uniform height. The volume of uniform height is approximately equivalent to that of the shaped volume. The laser beam shots are applied to the corneal tissue in a spatially distributed pattern spread over an area approximately equivalent to the surface area of the shaped volume to be eroded. The spatially distributed pattern extends the uniform shot pattern in fixed angles from a reference position on the shaped volume representative of the shaped volume's axis of symmetry. Shot density for the laser beam shots changes in correspondence with distance from the reference position.
