3D measurements of flame (IMAGE) Optica Caption A new high-speed 3D imaging method can capture the complex behavior of the turbulent flames produced during combustion. Shown are two cross sections of the 3D density measurement at Z = 16 mm and X= 0 mm, respectively(a) and the 3D iso-surface of the largest density gradient between the mixture and burned product (b).
