METHOD AND DEVICE FOR SURFACE EVALUATION |
摘要 |
Device and method for recording the visual properties of a surface, comprising an imaging device (3) for recording light interaction (reflection or transmission) with a surface, a light source (2), and a sample area for positioning a sample (6) with a surface to be examined. The imaging device, the light source, and the sample area are arranged in such a way that in one image at least one of the surface properties is recordable as a function of a continuous range of angles between the illumination direction (7, 9) and the observation direction (4, 5). The imaging device is a CCD camera. The device and method are suitable for imaging and evaluating visual properties which are dependent on the optical geometry, such as flop behaviour and gloss.
