The apparatus employs preconditioned radiation to detect defects having small radii of curvature or other such highly refractive surfaces and discriminate them from desirable markings having larger radii of curvature. The apparatus comprises a radiation source, means for selecting angular spectrum ranges, means for modifying average angles of incidence, radiation detection means and processing means.Other References
