This paper demonstrates the first simultaneous single-shot imaging of temperature and soot volume fraction, measured with nonlinear regime two-line atomic fluorescence (NTLAF) and laser-induced incandescence (LII), respectively. The measurements are performed in laminar premixed and nonpremixed flames, and in a wrinkled nonpremixed flame. No significant interference of the two measurements on each other is observed. This study demonstrates a major advance in the capacity to assess the interdependence of temperature and soot in flames of practical significance. © 2010 Published by Elsevier Inc. on behalf of The Combustion Institute.
