Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
The first step in collision avoidance is perception, which can use sensors like LiDAR, visual cameras, thermal or IR cameras, or solid-state devices. They are divided upon the part of the electromagnetic spectrum they use. There are two types of sensors, passive and active sensors. Examples of active sensors are LiDAR, Radar and Sonar. Examples ...
Hesai Technology (Hesai; Chinese: 禾赛科技; pinyin: Hésài Kējì) is a publicly listed Chinese technology company that engages in the development and sales of lidar products such as sensors. Its products are used mainly in the ADAS, vehicular automation, robotics and industrial sectors.
Lidar has a wide range of applications; one use is in traffic enforcement and in particular speed limit enforcement, has been gradually replacing radar since 2000. [1] Current devices are designed to automate the entire process of speed detection, vehicle identification, driver identification and evidentiary documentation.
Luminar Technologies, a maker of lidar sensors for self-driving cars, said on Tuesday that Tesla was the largest customer for its sensors in the first quarter, accounting for more than 10% of its ...
The LAS (LASer) format is a file format designed for the interchange and archiving of lidar point cloud data. It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The format is widely used [1] and regarded as an industry standard for lidar data.

Atmospheric lidar is a class of instruments that uses laser light to study atmospheric properties from the ground up to the top of the atmosphere. Such instruments have been used to study, among other, atmospheric gases, aerosols, clouds, and temperature.
