Abstract
A computer controlled system for determining various physical surface characteristics of an object includes a light source array, positioned to illuminate a surface for evaluation, in which individual lights in the array illuminate the object on a mutually exclusive basis, a radiometer, positioned to receive light from the object, producing image data relative to positions of the light pixels and a computer apparatus that, among other functions in the system, interprets the image data and determines at least the surface waviness, radius of curvature and cant angle of the surface.
