Question: 1 / 400

What is a key advantage of active LIDAR systems compared to passive systems?

Active systems are less expensive

Active systems require no power source

Active systems generate their own light

Active LIDAR systems generate their own light, which is a significant advantage over passive systems that rely on ambient light sources, such as the sun or moonlight, for operation. This capability allows active LIDAR to function effectively in a wider range of conditions and environments, including at night and in adverse weather conditions. The self-generated light means that active LIDAR can illuminate the target area with precision, enabling it to capture detailed information regardless of external lighting conditions. This feature makes active LIDAR particularly valuable for applications that require consistent, reliable data collection, such as topographic mapping, atmospheric studies, and various remote sensing tasks.
