Time-resolved (kHz) 3D imaging of OH PLIF in a flame
Based on scanning planar laser-induced fluorescence of OH, a measurement system with the capability to record time-resolved three-dimensional image sequences of the OH concentration and the flame front is demonstrated on a premixed flame. A dual-mirror scanning system is used to obtain equidistance between the illuminated planes. Non-uniformities in the laser sheet and laser absorption in the flam
