Surface finish scatters the light

Abstract

Outlines research work into the assessment of light‐scattering techniques for manufactured surfaces inspection. Describes the three type of commercial sensors that have been available so far: glossometers, peak intensity meters and light distribution measuring instruments and how they work. Describes the laboratory rig supporting equipment and analysis methodologies employed in order that numerous surfaces could be examined and classified. The outcome was an atlas of typical manufactured surfaces and a small ruggedized test bed sensor. Concludes that by using this rig and the atlas the whole 3‐dimensional light scatter image can be examined to select the appropriate sensor.
