LASER INDUCED INCANDESCENCE
• Goal: Qualitative and quantitative measurement of soot• Output: Soot profile, soot volume fractions, and particle size• Principle:
– Soot is heated by laser (3500-4000K)– Incandescence flame images soot profile– Incandescence intensity soot volume fraction– Temporal decay of incandescence particle size
