(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.
