The Karlsruhe Center for Material Signatures KCM is an association of institutes of Karlsruhe Institute of Technology (KIT) and the Inspection and Optronic Systems business unit of Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB. With modern analytic technology, we visualize spectral information of materials. KCM identifies the specific spectral signatures of your material. No matter if for food, plastics or minerals. Each material has it's own specific spectral signatures. We develop solutions for sorting and concentrating of your materials, and use the spectral signatures.

We are happy to identify the signature of your materials. Contact us!



We analyse your materials, to identify the specific spectral signatures. With modern laboratory equipment and optimized dataprocessing, experts identify the spectral signatures. Basing on this, we find the separation or concentration technology, that is needed.



Within this chapter you will find actual publications about hyper spectral analysis of materials. This publications give also an overview to the state of scientific, about spectral image and signal processing.

Analysis Cooperation

Due to the application of special knowledge of the participating partners from different disciplines, we are in a position to identify specific signatures of objects in your samples.

KCM and KIT organize the international Conference OCM, which takes place every two years in Karlsruhe. The topic of the conference is the optical characterization of materials.

Image Processing Forum

KCM and KIT organize the FBV, which takes place every two years in Karlsruhe. The forum aims to report on current trends on solutions in image processing and to contribute to the professional exchange between the participants.
