two-color, volumetric laser-induced fluorescence (TC-VLIF) was demonstrated for three-dimensional, tomographic imaging of the structural properties of the OH radical and temperature field in a turbulent hydrogen-air flame. Two narrow-band laser sources were tuned to the Qi(5) and Qi(14) transitions of the (1,0) band in the A2E<—X2II system and illuminated a volumetric region of the flame. Images from eight unique perspectives collected simultaneously from each of the two transitions were used to reconstruct overlapping 011 fields with different Boltzmann fractions and map the 3D temperature distribution with nanosecond precision. Key strategies for minimizing sources of error, such as detector sensitivity and spatial overlap of the two fields, are discussed.
