Laser-Induced Incandescence (LII) is a technology that offers a reliable means for spatially and temporally measuring the soot (black carbon, elemental carbon) concentration and primary particle size in engine exhausts and in ambient air.
The High Speed Imaging (HSI) Flight Probe, Dual-Range (FPDR), an innovative imaging-based instrument, has been developed specifically for aircraft-based icing cloud studies that require precise measurement of liquid droplets and ice crystals in mixed-phase environments.
