Light Detection And Ranging (LiDAR)

How does LiDAR work in cars?

LiDAR stands for ‘light detection and ranging’. 

It is a type of sensor that works in a similar way to radar, but instead of using radio waves it sends out pulses of infrared light millions of times a second, and measures how long they take to come back after bouncing off objects close to it. This allows it to build a form of constantly changing 3-D map of what is around it.

LiDAR is becoming more commonplace on modern cars, as they adopt driver assistance systems that will be the basis of autonomous driving.
