A highspeed nir-spectroscope to investigate ignition and combustion of propellants and pyrotechnics
A high speed NIR emission spectrometer on the base of an acousto optical tuneable filter (AOTF) is presented that detects up to 1000 spectra per second in the wavelength range 1.25 - 2.6 µm with a resolution of less than 7 nm. As examples spectra series of a pulsating nitromethane pool fire as well...

| Zusammenfassung: | A high speed NIR emission spectrometer on the base of an acousto optical tuneable filter (AOTF) is presented that detects up to 1000 spectra per second in the wavelength range 1.25 - 2.6 µm with a resolution of less than 7 nm. As examples spectra series of a pulsating nitromethane pool fire as well as moving and burning droplets were acquired and analysed. |
