Process for the identification of randomly shaped and/or plane materials by determination of the structure of the materials through application of electromagnetic and/or acoustic waves

摘要

Acoustic or electromagnetic wave energy (UV-, visible or infrared, preferably electromagnetic, particularly UV- or visible) is applied to randomly-shaped or plane materials or mixtures of such materials, whereby the materials are irradiated and the structures of the materials, particularly the surface structures of the materials, are determined by identification of the waves which arrive from the irradiated materials at a receiver-sensor, equipped with a data logger, and comparison of the thus-received data with the data of the data logger. A sorting device for sorting out thus-identified materials is operated with the aid of signals arriving from the receiver-sensor.
