Today, a groundbreaking new technology has been announced that could revolutionize the field of radar and lidar. Researchers have created a coherent two-photon lidar rangefinder that can accurately measure distances up to 10 meters away with incredible precision. Unlike conventional lidar, this new technology uses two-photon absorption to detect the distance between objects, allowing it to measure distances with accuracy down to the millimeter. This new breakthrough could dramatically improve the accuracy of autonomous vehicles, drones, and robots, as well as many other applications.
