Laser-induced-incandescence (LII) for particle sizing behind shock waves
Laser-induced-incandescence (LII) is a relatively new optical diagnostic for particle sizing which is currently used in combustion science. Its advantage is the possibility of getting size information with high time and space resolution even for nano-particles. LII is based on fast heat-up of particles by a short laser pulse and on the observation of the subsequent thermal radiation during particle cooling back to the surrounding gas temperature. Larger particles with larger volume to surface ratio need longer time to cool down than smaller ones. This basic principle of LII was first suggested by . In the work of [2, 3, 4] the completely measured time-resolyed particle radiation was used to determine the particle size distribution.
