    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.

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.
