ABSTRACT:
A method for determining a surface topology of a workpiece preferably comprising a general symmetric asphere. The method includes the steps of coupling a projectile to a surface of a workpiece, and imparting a trajectory to the projectile with respect to the surface; sensing the trajectory of the projectile with respect to the workpiece surface, for assessing a locus of positional points over time of the projectile, the locus being a measure of the surface topology of the workpiece; and computing from the locus of positional points over time, the surface topology of the workpiece.
