PCT No. PCT/DE87/00239 Sec. 371 Date Dec. 30, 1987 Sec. 102(e) Date Dec. 30, 1987 PCT Filed May 26, 1987 PCT Pub. No. WO87/07369 PCT Pub. Date Dec. 3, 1987.A method for measuring volume of surface depressions wherein the depression to be measured is or filled with a material which emits wavelength-shifted scatter light under irradiation. The material is illuminated with a light source whose wavelength lies in the absorption region of the material and the wavelength-shifted intensity of the scatter light of the material excited by the light source is measured with a photodetector, whereby the measured intensity is a measure of the volume of the surface depression.
