Active optical sensor technology
Abstract
An account is given of the development status, performance capabilities, and prospective applications of lidar systems in earth remote sensing, as envisioned by researchers at NASA-Marshall, NASA-Goddard, NASA-Langley, and NASA-Wallops Island. Lidar systems can conduct measurements in research efforts concerned with wind fields, altimetry, ozone depletion, water vapor mixing ratios, temperature and pressure, phytoplankton chlorophyll fluorescence, forest folliage, and ice sheets. It is in all cases that lidar lasers be lightweight, compact, and efficient; most lasers need to be tunable. Detectors used range from photomultipliers to photodiodes.
