  5. 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 NASA Grant URC NCC NNX08BA44A NASA Grant URC NCC NNX08BA44A 5
