Researchers have developed a coin-sized laser that they say could help improve how self-driving cars navigate the roads.
The device is designed to improve a scientific technology known as optical metrology, which uses light to measure and identify objects.
The scientists envision a variety of uses for their invention, including lidar (light detection and ranging) that would feed autonomous vehicles real-time data for safe navigation.
