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.


an instrument that detects the position or motion of objects and which operates similarly to a radar, but which uses laser radiation rather than microwaves


(ˈlaɪ dɑr)

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]
