DEVICE AND METHOD FOR MEASURING THE DIMENSIONS OF A THREE-DIMENSIONAL SURFACE STRUCTURE

摘要

The invention concerns a device for measuring the dimensions of a three-dimensional surface structure, in particular folds in the human skin (9). The device has a transparent support plate (2) designed to hold initially liquid silicone material (3) to produce a silicone impression of the surface being examined. The device also has an analysis unit for analysing the surface structure of the impression. The invention calls for the support plate (2) to have a measurement zone (4) held at a given distance from the surface under examination (9), for the silicone material (3) which is introduced into the measurement zone to be uniformly coloured and for the support plate (2) to have at least one drainage channel (10) leading away from the measurement zone (4) for excess silicone material (3). Analysis of the silicone impression is carried out by determining the light absorbtion of the impression from light-intensity measurements.
