7 September 2006 FireLidar development: light scattering from wood smoke experiments and theory at 1574 nm

Measurements and lidar calculations have been made for 1574 nm laser light pulsed through hydrocarbon smoke generated by wood. A pulsed laser signal is directed to the end of wood smoke filled chamber. The signal is reflected back through the smoke by a mirror and the end of the chamber and the total returned energy is measured as a function of the smoke density. The results are compared with a lidar calculation using Rayleigh-Debye-Ganz scattering theory for fractal aggregates. Measurements and calculations are also made of the total backscattered signal for a smoke chamber with a non-reflecting surface. Relatively good agreement between the theory and experimental results are achieved in both cases. These results are used in the feasibility studies of a FireLidar active imaging system being developed for use in search and rescue in smoke and flame environments.
