Process and installation for the identification of materials |
摘要 |
Materials are exposed to laser energy, and after the material is heated, the thermal radiation of the material is measured. Following this, a material-specific evaluation takes place, based on optical and thermal material properties. At least one area on the surface of the material to be identified is subject to a short, point-shaped exposure of laser radiation. The material-specific thermal impulse response for the radiated surface area of the material is both locally and temporally measured, and evaluated as regarding the kind of material.
