This mini chip-sized LiDAR can fit on your fingertip!
LIDAR, which stands for Light Detection and Ranging, is a surveying method that measures distance to a target by illuminating the target with laser light and measuring the reflected light with a sensor. While LIDAR is used in a variety of fields ranging from construction to disaster response (Also Read: Use of LiDAR in disaster response), it is critical for autonomous vehicles and robots as it helps them to sense the world around them. However, a long-standing problem with LiDAR has been its size — remember large spinning LiDAR sensors fitted on top of vehicles.
