Ultrafast 2D maps of flame temperature imaged by LS-CUP at 1.25-Gfps.

Caption

a, Spatiotemporal dynamics of flame temperature when excited by a single nanosecond light pulse. The temperature is calculated by taking laser-induced incandescence signals from two distinct color channels. b, Spatially averaged temperature evolution and its exponential fit, showing a rapid cooling after laser excitation.
