Towards high-speed raman spectroscopy for industrial sorting applications

Abstract

A real-time Raman mapping system for detecting and discriminating a range of industrially relevant materials such as glasses and various minerals is presented. The system is built from components that are suitable for industrial conditions. Together with a signal processing and a chemo-metric model, the system was shown to be capable of discriminating between the test materials. We argue that the approach is a novel alternative to established sorting sensors.
