A system for treating the surface of an object comprising at least first and second surface segments with a varying depth between the first and second surface segments, the system comprising:
- a laser for applying a uniform surface treatment to both the first and second surface segments of the object;
- an optics system for directing the laser with respect to the object;
- and
- a focus control mechanism for modulating the focal point of the laser with respect to the object surface.
A method of treating a surface of an object comprising at least first and second surface segments with a varying depth between the first and second surface segments, the method comprising:
- applying a uniform surface treatment to both the first and second surface segments in a single operation;
- modulating the focal length of the uniform surface treatment with a focus control mechanism.
A system for treating the surface of an object comprising an irregular surface, the system comprising:
- a sensor for mapping the object irregular surface to obtain control data;
- a laser for applying a surface treatment defined by the control data;
- an optics system for directing the laser with respect to the object;
- and
- a focus control mechanism for modulating the focal point of the laser with respect to the object surface.
