1. An assembly for determining a surface topology of a workpiece, said assembly comprising:
- (a) a projectile;
(b) means for coupling the projectile to the workpiece surface and for imparting an initial momentum to the projectile with respect to the surface;
(c) an electronic camera including a megapixel two-dimensional array positioned to view the surface normal to the surface, said camera recording relative movement of the projectile with respect to the surface including a locus of at least hundreds of positional points over time of the projectile on the surface; and
,(d) means using said locus of positional points for determining the surface topology of the workpiece.

Abstract
An assembly preferably utilized in cooperation with a method for determining a surface topology of a workpiece. The assembly includes a projectile; means for coupling the projectile to a surface of a workpiece, and for imparting an initial momentum to the projectile with respect to the surface; and, means for sensing a relative movement of the projectile with respect to the workpiece surface, for generating a locus of positional points over time of the projectile as a measure of the surface topology of the workpiece.
