Time-resolved laser absorption imaging of ethane at 2     kHz in unsteady partially premixed flames

In this work, laser absorption imaging is expanded in temporal resolution capability to kilohertz measurement rates by coupling sparsely sampled wavelength scanning and digital image postprocessing for diffraction correction. The setup employs an interband cascade laser near 3.34   μ m ...
