Why does LiDAR have a specific wavelength? Part.2
Another specificity of LiDAR wavelength: atmospheric absorption. A sun beam emits up to 150K lux. It is like receiving light from 15,000 candles at the same time. One that is direct or reflected, can be misinterpreted by the LiDAR and be considered as a laser return. The water molecules in the atmosphere absorb a good […]
