Improvement in soot concentration measurements by laser-induced incandescence (LII) through a particle size correction

摘要

layed detection, but also for prompt detection one can expect a significant influence on results for strongly differing particle sizes. If particle sizes are known, LII concentration measurements may be considerably improved by correct weighting of data on the basis of primary particle sizes. While the numerical value of the exponent to be used for this correction naturally depends on the respective experimental conditions, the approach presented may be used as a practical guideline.
