File Police LIDAR Gun 0946.jpg thumb right Police officer using a hand held LIDAR speed gun A LIDAR speed gun is a device used by the police for speed limit enforcement which uses LIDAR to detect the speed of a vehicle. Unlike Radar speed gun s which rely on doppler effect doppler shifts to measure the speed of a vehicle these devices allow a police officer to measure the speed of an individual vehicle within a stream of traffic. How it works LIDAR relies on the principle of time of flight of a laser beam to calculate the speed of the target object. Devices typically send out a stream of approximately 100 pulses over the span of three tenths of a second. The reflected signals are then processed using statistical algorithm to picks and which reflected signals to retain. The use of many reflections and an averaging technique in the speed measurement process increase the integrity of the speed reading. Vehicles are usually equipped with a horizontally oriented Vehicle registration plate registration plate that, when illuminated, causes a high integrity reflection to be returned to the LIDAR despite the shape of the vehicle. In locations that do not require that a front or rear registration plate is fitted, headlamps and rear reflectors provide almost ideal Retroreflector retro reflective surfaces overcoming the reflections from uneven or non compliant reflective surfaces thereby eliminating sweep error. It is these mechanisms which cause concern that LIDAR is somehow unreliable. LIDAR does not suffer from sweep error when the operator uses the equipment correctly and when the LIDAR unit is equipped with algorithms that are able to detect when this has occurred. A combination ... the received signal strength to be changed then the LIDAR unit will reject the measurement thereby producing speed readings of high integrity. For LIDAR units to be used in law enforcement applications ... a BBC program Inside Out BBC TV series Inside Out demonstrated how the LIDAR speed gun most commonly ... more details
