LRF

Acronym for Laser Range Finder. It is a device used to measure distances. Most laser rangefinders operate on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender.
Some Higher end Laser Rangefinders are able to achieve millimeter level precision.
Even over long distances.
