METHOD AND SYSTEM FOR DETERMINING THE POSITION AND ALIGNMENT OF A SURFACE OF AN OBJECT IN RELATION TO A LASER BEAM

WIPO Patent Application WO2004032810

A3

The present invention generally relates to a method and system for determining the position and alignment of a plane in relation to an intersecting axis and using that known position and alignment to allow for corrections to be made when using the plane as a reference plane. More particularly, the invention relates to a method and system for determining the angle of tilt of a planar surface in relation to a laser beam, and using the determined angle of tilt to calculate a correction factor to be applied to the laser beam. Briefly stated, the method and system ultimately calculates a correction factor, z-offset, that is applied when using the laser beam in a procedure.
