METHOD AND DEVICE FOR ANALYSING VISUAL PROPERTIES OF A SURFACE

摘要

A method for imaging a sample by means of a device having a cavity with black inner walls and a sample opening, the device further comprising illumination means for illumination of the cavity and a digital imaging device directed from the cavity to the sample opening, the method comprising the following steps : - presenting a sample to the cavity via a sample opening; - illuminating the cavity; - activating the imaging device to record an image of the sample; - communicating the recorded image data to a computer programmed with image analysis software to analyze the recorded image, characterized in that the inner wall of the cavity is light absorbing and in that it is at least partly provided with light point sources distributed over at least a part of the inner wall of the cavity and a selection of the light sources, dependent on the desired light conditions, is activated.
