From: 3D flame reconstruction and error calculation from a schlieren projection
Slices of the reconstructed 3D volume of a flame (the cuts were made at the half value corresponding to pixel 100 at the x axis). The reconstructed volume of flame represents the temperature distribution in 3D for the four data sets: a) 1OS, b) 2OS, c) 3OS and d) 4OS, colors correspond to the temperature intensity which goes from blue (cold) to red (hot). The x and z axes correspond to the original x and y axes of the experimental data, respectively. The new axis obtained due to the 3D reconstruction is the rotation axis
