APPARATUS FOR SURVEYING THE THERMAL TOPOGRAPHY OF A SURFACE, IN PARTICULAR OF HUMAN SKIN |
摘要 |
Method and apparatus for surveying the thermal topography of a surface, in particular of human skin, wherein a layer (14) of liquid crystals having cholesteric properties is applied in contact relationship to the area to be surveyed. The area to be surveyed is then illuminated with a light (18) having a wavelength in the visible spectrum range, and of shooting with a photographic camera (1) a number of photograms taken at various wavelengths in the visible range. The camera (1) is mounted for adjustment with respect to the layer (14) of liquid crystals which covers the area to be surveyed, at least one filter (16) is interposable between the objective (3) of the camera (1) and the layer (14) of liquid crystals. The apparatus includes a light source (18) adapted for emitting either a monochromatic light or a discontinuous spectrum light in the visible range of the spectrum, which impinges on said layer (14) of liquid crystals. |
