Abstract
The differential reflectance of several naturally occurring and man-made materials at CO2 laser wavelengths is determined. The computer-controlled measurement system has two CO2 lasers and determines the differential reflectance of each material by measuring the ratio of the reflected signals at two wavelengths simultaneously. These results can be used to improve the accuracy of air pollution measurement systems which derive their return signals from topographic targets.Keywords
