We report three-dimensional index-of-refraction measurements in a methane–air slot diffusion flame and a methane–air slot subsonic jet using beam-deflection optical tomography. The horizontal and vertical spatial resolutions are 0.26 and 0.635 mm, respectively. The peak temperature is calculated from the index-of-refraction map for the flame and compared with thermocouple temperature measurements.
