The speed measurement accuracy of the laser radar is verified by using speed surveys performed by the host agency.
Scanning infrared laser radar two-beam pattern across a traffic lane.
The department is currently utilizing mounted moving radars, handheld radars, and a couple of infra-red laser radar units.
The system uses a combination of millimeter wave and laser radar sensors, plus in-pavement loops to detect other vehicles.
laser radar in Science
A method of detecting distant objects and determining their position, velocity, or other characteristics by analysis of pulsed laser light reflected from their surfaces. Lidar operates on the same principles as radar and sonar.
The equipment used in such detection. See also Doppler effect, radar, sonar.
