Discrimination of Metallic and Colored Surface States by Optical Pattern Projection Method

摘要：

In the optical pattern projection method called by the authors for surface roughness measurement, the roughness is detected from the qualities of the output image,such as contrast,formed by an imaging system including a target surface. We will report the relation between the roughness and contrasts for metallic surfaces and the colored plastics in the range of Ra of about 0.1 μm and below,using a video camera. For the colored plastic surfaces, the authors explain that the sensitivity for gloss depends on the contrast of the formed image under additional illumination by other light sources.
