Fast Emission Spectroscopy for a Better Understanding of Pyrotechnic Combustion Behavior

Pyrotechnic mixtures react mostly fast and under a high release of thermal energy and heat radiation. A spectral analysis of this emission allows deep insight into the reaction process by the non-intrusive determination of the reaction temperatures and observation of the main reaction species and their concentrations. In the presentation various pyrometric and spectroscopic measurement techniques and data analysis and interpretation procedures are introduced using the spectral range form the ultraviolet, visible and near to medium infrared in combination with image processing of video and IR-camera signals.
