Origin of lidarli(ght) + (ra)dar
- 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.
- The equipment used in such detection. In both senses also called laser radar.

lidar - Computer Definition
(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 and the measurement of atmospheric conditions. LIDAR works by transmitting 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 does not technically use "radio" waves (see radar). See autonomous vehicle.
