| Abstract |
The report describes the work performed to develop an eyesafe CW lidar for remote measurement of the opacity of smoke plumes from industrial smoke stacks. The analysis, design, construction, and evaluation of a laboratory model CW lidar were performed to determine the limitations and potential of the technique. The proof-of-principle experiments combine what is called an FM-CW radar technique with an argon laser. The technique involves modulating the intensity of the laser beam at a frequency that changes rapidly and linearly with time. A portion of the transmitted signal is mixed electronically with the light reflected from the targets in a device similar to a radio receiver. Each target appears at a particular frequency. By tuning the radar's receiver to these target frequencies, the researchers were able to measure both the range and the opacity of semi-transparent targets over distances of 100 to 200 meters. |
