The field of optical and laser remote sensing has grown rapidly in recent years. This dynamic growth has been stimulated not only by technological advances in lasers, detectors, and optical system design, but also by the potential application of remote sensing systems to a wide variety of atmo- spheric measurements. Optical and laser remote sensing can allow single- ended measurement capability not offered by conventional point-detection techniques. While many past measurements have been associated with labo- ratory research. practical systems have recently been developed which are capable of...
