Can Lidar Penetrate Water?

Yes, lidar can penetrate water but can be quite a challenge. Mainly due to various limitations such as refraction and light absorption. Greenlight (infrared wavelength of 532nm) from Lidar sensors can penetrate water the best and farthest due to its wavelength. It can penetrate ocean water of up to hundreds of meters (up to 300m).  …

Differences between the Lidar Systems and Depth Camera

Image source: extremetech.com Lidar systems and depth cameras have become part of today’s depth-sensors in the digital market. The sensors supplement the current monocular RGB images by providing per-pixel depth information of the target objects. The depth- sensors accurately measure the distance and wavelength of a target object and return a 3D representation. Although the …
