The Detection of Distant Aerosols and Spray Clouds by a Lidar System Based on the Carbon Dioxide (CO2) Laser
Abstract
The feasibility of the use of a CO2 lidar system in various weather conditions for the detection of distant aerosols and sprays is considered, with the main emphasis on the detection of spray from high speed aircraft. A comparison is made of the known performance of the CDE ruby lidar with the performance of CO2 lidars based on laser powers and detectors likely to be practicable in the immediate future. It is concluded that the CO2/TGS lidar system would be inferior in performance to the ruby system but the CO2/PbSnTe system would appear to offer advantages in lower required power output and in higher repetition rate for the same detection range. Details are given of the technical parameters about which more reliable information is required before a more accurate appreciation of the problem can be completed.
