Bathymetric LiDAR - USGS
Bathymetric LiDARs, which employ a blue-green wavelength of laser light to penetrate water, currently remain a very specialized and unique technology with only a handful of these systems currently in existence, and their use almost exclusively relegated to coastal waters.

2023年9月7日 · The Japanese company Amuse Oneself has developed TDOT GREEN, a lightweight green laser LiDAR technology that can be mounted on drones for aerial surveying applications.
The Use of Green Laser in LiDAR Bathymetry: State of the Art and …
2022年12月27日 · The green laser can penetrate the water, which makes it possible to measure the depth of shallow water reservoirs, rivers, and coastal sea waters within three Secchi depths. This article presents the theoretical basis for the construction of a green laser.
Green-wavelength lasers can penetrate through water to provide submerged topography For bathymetric lidars, tradeoffs exist between laser power, pulse width, and footprint size. Absorption and scattering cause an exponential decay of light intensity with increasing depth. Habitat spectra / bottom composition (sand vs. sea grass
The Use of Green Laser in LiDAR Bathymetry | Encyclopedia MDPI
The green laser’s ability to penetrate water has been used in LiDAR air bathymetric systems (acronym for “light detection and ranging”). LiDAR scanners consist of several components. Of course, you need a light source, a laser diode, and its receiver that measures the light reflected from the scanned object.

2023年11月4日 · Topographic LiDAR uses infrared lasers at 1064 nm to map out the surface of the Earth while bathymetry uses green lasers at 532 nm to map out the seafloor. The difference of wavelength allows the LiDAR technology to measure the land accurately in varying conditions as green lasers are better at penetrating water.
