¦ noun a detection system which works on the principle of radar, but uses light from a laser.
1960s: blend of light1 and radar.



Lidar (, also LIDAR, or LiDAR; sometimes LADAR) is an acronym of "light detection and ranging" or "laser imaging, detection, and ranging". It 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. It is sometimes called 3-D laser scanning, a special combination of 3-D scanning and laser scanning. LIDAR has terrestrial, airborne, and mobile applications.

Lidar is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. It is used to make digital 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has also been increasingly used in control and navigation for autonomous cars and for the helicopter Ingenuity on its record-setting flights over the terrain of Mars.

Examples of use of LIDAR
1. Les ingénieurs d‘Enviroscopy, société issue du Laboratoire de pollution atmosphérique et des changements climatiques de l‘EPFL, veulent développer un Lidar non seulement bon marché, portable mais facile d‘utilisation.
2. Certains d‘entre eux devraient ętre de plus en plus diffusés dans le futur, ŕ l‘exemple du Lidar (Light Detection and Ranging) ou du DOAS (Differential Optical Absorption Spectroscopy). La ville de Gen';ve, par exemple, a remplacé une partie de ces stations fixes par des DOAS, un syst';me optique qui enregistre en continu les concentrations des principaux polluants atmosphériques.
3. Il s‘agit d‘un faisceau de lumi';re ŕ l‘horizontale qui évalue sur une distance de 200 ŕ 500 m';tres environ la concentration d‘oxyde d‘azote (NO2), d‘ozone (O3), de dioxyde de soufre (SO2) et quelques–uns des composés organiques volatils (COV). Autre instrument: le Lidar.
