Abstract: Laser-based diagnostics provide powerful and unique capabilities for non-intrusive measurements in reactive flows. This paper will overview recent progress in the evolution and application of two of the most important diagnostic concepts: tunable diode laser (TDL) absorption, which is a line-of-sight technique with continuous recording potential; and planar laser-induced fluorescence (PLIF) imaging, which yields instantaneous measurements at a large number of points in a plane illuminated by a pulsed laser. Techniques based on these measurement concepts can monitor multiple parameters including species concentrations, temperature, pressure and velocity. Example results will be shown for TDL measurements in a pulse detonation engine and for PLIF imaging in an expansion tube study of supersonic combustion.
