   Sammanfattning : The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. LÄS MER

7. 5. Towards Quantitative Diagnostics using Short-Pulse Laser Techniques

   Författare :Andreas Ehn; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PicoSecond Laser Diagnostics; Raman Scattering; Photo Fragmentation; Fluorescnece Lifetime Imaging; Temporal Filtering; Fysicumarkivet A:2012:Ehn; LIDAR; Laser-Induced Fluorescence;

   Sammanfattning : Laser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena that affects the research of interest.
