摘要
An improved method and an improved device for carrying out an optical comparison between at least two samples, preferably by comparing sections that can be selected, is characterized by the following characteristics: the sample (UR, LE, I) that is to be examined and is characterized by a non-uniformity in the structure and/or color is illuminated by diffused light; from the light reflected by the sample (UR, LE, I) to be examined, an interference spectrum is created by means of a spectrometer; the interference spectrum created by the spectrometer is depicted on a camera; the interference spectrum obtained in this way and/or values of the sample (I) to be examined derived therefrom are used as sample values which are compared to sample values of a reference sample (UR, LE) obtained accordingly.
