Abstract

The integrated backscatter signal from a smoke cloud contained in a chamber is studied as function of the measured concentration. An analysis based on the total backscattered signal leads to the determination of calibration curves specific to the material and to the lidar system. This procedure leads to a lidar inversion technique based on a calibrated total integrated backscatter curve. The limitation of the technique is discussed in terms of the maximum optical depth permitted for acceptable results.
