Objective measurement and characterization of scratch standards

Published

Author(s)

M. Young

Abstract

The manufacture of scratch standards for use with MIL-0-13830A has been hampered by the lack of an objective measurement technique, The U.S. National Bureau of Standards has therefore undertaken a comprehensive program to provide quantitative measurements of the light scattered by the scratches and to correlate them with assessments made by trained observers. In this paper, I apply scalar diffraction theory to developing design criteria for a polar scanning apparatus, describe an apparatus that includes a novel optical system, and show scans from one full set of secondary standards. Comparing these scans with the visual assessments is not straightforward.
