Diode-laser random-modulation cw lidar
Abstract
Practical lidar applications require an easy to operate compact system. Random-modulation continuous-wave (RM-CW) lidar makes it possible to use a CW laser with a power level of several tens of milliwatts as the light source. For this purpose, the diode laser is the most suitable candidate for a compact lidar system. Construction of a practical portable diode-laser RM-CW lidar system and its measurement of the spatial aerosol profile at nighttime are reported. The low-level CW power and the current operational wavelength (780 nm) make the RM-CW lidar completely eye-safe by ANSI standards.
