what is lidar

LiDAR, or Light Detection and Ranging, is the tech equivalent of a bat's echolocation but using lasers instead of squeaks. It fires out laser pulses to measure distances by timing how long it takes for the light to bounce back. In the automotive world, LiDAR helps self-driving cars see their surroundings in 3D, mapping obstacles with precision down to a few centimetres. It's a key player in advanced driver-assistance systems (ADAS), aiding in collision avoidance and adaptive cruise control. While it sounds like sci-fi wizardry, it's become a staple on some high-tech vehicles. For the nitty-gritty specs, best check the official manuals or industry whitepapers.
