The incredible shrinking LiDAR

The term LiDAR comes originally from the mixture of the words light and radar, although it also responds to acronyms such as light detection and ranging or laser imaging, detection, and ranging, or sometimes replaced by the term 3D laser scanning. Basically, we are talking about a method using terrestrial, aerial and mobile applications to measure distance ranges by hitting the target with laser light and measuring the reflection with a sensor, so that the differences in laser return times and wavelengths can be used to make 3D digital representations of the target.
