LiDAR (light detection and ranging), is a remote sensing technology that emits continuous laser pulses to calculate the position of objects in the surrounding environment.
LiDAR is an acronym for Light Detection and Ranging. In LiDAR, laser light is sent from a source (transmitter) and reflected from objects in the scene. The reflected light is detected by the system receiver and the time of flight (TOF) is used to develop a distance map of the objects ...
LiDAR works on the same principles as radar ("radio detection and ranging," a location system that is often used by ships and planes) and sonar ("sonic navigation and ranging," a system that is typically used by submarines). All three technologies emit waves of energy to detect and track ...
LiDAR is a mapping technology that uses laser light to measure the distance to a target surface. In a nutshell, it's generating a 3D map of anything from a room to large areas of terrain with stunning accuracy. In this article, we’ll look at what LiDAR solutions are capable of, what...
Short for Light Detection and Ranging, LiDAR is a remote sensing method that irradiates objects using near-infrared, visible, or UV light then detects the reflected light with an optical sensor to measure the distance. Also called Laser Imaging Detection and Ranging, it is often used to measure...
Introduced in the 1960s, LiDAR technology originally measured large areas of terrain by mounting scanners to airplanes. Like Radar (Radio Detection and Ranging), this is achievable by emitting pulses toward the surface of the ground and bouncing them back to a sensor. Originally referred to as ...
Lidar point cloud of a road scene. This market adoption of lidars is driven by three key reasons: Low-cost lidars The introduction of low-cost lidars, with enhancement in characteristics such as range, size, and robustness, have increased the availability of the technology for comparatively low...

Amplitude-modulated continuous wave (AMCW) LiDAR is similar to the basic time-of-flight system in that the AMCW LiDAR emits a signal that measures the time of the laser reflection back. The difference, however, is that time-of-flight systems emit only one pulse, and AMCW LiDAR modulates by...
