li·dar L0154650 (lī′där)n.1. An optical sensing technology used to determine the position, velocity, or other characteristics of distant objects by analysis of pulsed laser light reflected from their surfaces.2. The equipment used in such detection. In both senses also called laser radar.
[li(ght) + (ra)dar.]lidar (ˈlaɪdɑː) nan instrument that detects the position or motion of objects and which operates similarly to a radar, but which uses laser radiation rather than microwavesli•dar (ˈlaɪ dɑr)
n. a device similar to radar but using pulsed laser light instead of radio waves to detect particles and varying conditions in the atmosphere. [1960–65; presumably li (ght1) + (ra) dar] Thesaurus| Noun | 1. | lidar - a measuring system that detects and locates objects on the same principle as radar but uses light from a laser; a potential technology for detecting air turbulence that can affect aircraftmeasuring device, measuring instrument, measuring system - instrument that shows the extent or amount or quantity or degree of something |
TranslationsLIDAR
lidar[′lī‚där] (optics) An instrument in which a laser generates intense infrared pulses in beam widths as small as 30 seconds of arc; beam reflections and scattering effects of clouds, smog layers, and some atmospheric discontinuities are measured by radar techniques; it can also be used for tracking weather balloons, smoke puffs, and rocket trails. Derived from laser infrared radar. LIDAR(LIght Detection And Ranging) An optical technology that senses the shape, motion and makeup of objects in the environment. It is used in a wide variety of disciplines, including airborne mapping, measuring atmospheric conditions and self-driving cars. LIDAR works by pulsing laser signals using all light ranges (ultraviolet, visible, infrared) and amplifying the light that is scattered back through an optical telescope and photomultiplier tube. Sometimes called "laser radar," LIDAR technically uses light waves and not "radio" waves (see radar). See self-driving car.
