A method for identifying, and / or quantifying a material or material mixture is claimed, wherein the material or the material mixture contains one or more component (s) X which can be identified by means of photosensory, spectroscopic and / or imaging methods, and / or is quantifiable, which method comprises the steps of generating one or more signal (s), spectrum and / or image by excitation with a radiation source and recording by means of optical sensors, photodiodes, cameras, spectrometer systems and / or hyperspectral cameras of the component ( n) X under defined excitation conditions, - evaluating the signals obtained, the spectrum and / or image obtained and assigning the spectrum and / or image to a component X and subsequently to a material or material mixture, - determining the quantitative portion by mathematical operations in relation to a determined reference value / ratio / signal l / -spektrum to uncut and defined as a reference product. |
