One key technology making its way into a variety of autonomous research vehicles is Light Detection and Ranging (LIDAR) technology. It's also the core technology for Google's autonomous vehicle. LIDAR uses rotating lasers that emit short pulses of light and then measures the return time to create a detailed 3D map of the surrounding environment. The LIDAR on Google's vehicle, which is also used by Ford and others, is a popular model built by Velodyne LiDAR that has 64 lasers spinning at 900 rpm, providing 2.2 million data points per second, enabling the creation of a detailed 360 degree 3D map
