Development of a picosecond lidar system for large-scale combustion diagnostics.
(2009) In Applied Optics 48(4). p.65-72- Abstract
- In the present work, a picosecond lidar system aiming at single-ended combustion diagnostics in full-scale combustion devices with limited optical access, such as power plants, is described. The highest overall range resolution of the system was found to be <0.5 cm. A demonstration has been made in a nonsooty and sooty Bunsen burner flame. A well-characterized ethylene flame on a McKenna burner was evaluated for different equivalence ratios using Rayleigh thermometry. The results indicate both that picosecond lidar might be applicable for single-shot Rayleigh thermometry, even two-dimensional, and that there is a possibility to qualitatively map soot occurrence. Furthermore, differential absorption lidar has been investigated in acetone... (More)
