What is the primary function of lidar systems?

The primary function of lidar systems is to measure distances using laser light. Lidar, which stands for Light Detection and Ranging, operates by emitting laser pulses and measuring the time it takes for the light to bounce back after hitting an object. This time of flight allows the system to calculate how far away the object is. This distance measurement capability is essential for various applications including topography mapping, autonomous vehicles for navigation, and environmental monitoring.

The technology leverages the precision of laser beams to provide highly accurate and detailed information about the surrounding environment, which is why it is widely used in fields such as geography, mining, forestry, and even robotics.

Other options, while related to different technological functions, do not pertain to the core purpose of lidar systems. For instance, monitoring weather patterns is typically the realm of meteorological instruments rather than lidar technology. Detecting radar signal interference and transmitting/receiving radio frequency signals refer to radar systems and communication technologies, which are distinctly different from the principles behind lidar.
