What is the definition of LiDAR?
Stands for light detection and ranging. Lidar systems detect and measure the distance to objects or surfaces through lightwave reflection and detection. Lidar technology uses electromagnetic radiation in the infra-red and visible light spectrum, which are much higher frequencies than that of radio or microwaves. Lidar uses a high-accuracy timing device to measure how long it takes from the time that the emitted electromagnetic radiation to travel both to and from the object or surface. Using this duration and the speed of the radiation, the range can be accurately calculated.
