Abstract
The invention relates to a device and method for monitoring a chemical reaction proceeding from a first state to a second state by emitting and detecting radiation in ranges of interest for a spectral signature of the material undergoing the chemical reaction. Using the concept of optical spectral detection and identification, it is therefore possible to utilize a combination of specific emitters and detectors, optics and signal processing in order to identify materials and events.
