Abstract
A system for measuring optical characteristics of a surface such as orange peel includes a light source and detector retained upon a support block and translatable as a single unit. The light source emits a beam which is scanned across the workpiece surface by a moving mirror so as to produce a scan line. Translation of the light source causes the scan line to move across the workpiece. The associated detector reads the light reflected from the workpiece and produces a signal which may be processed to determine orange peel or other optical characteristics of the surface.
