What does LIDAR stand for?

LIDAR stands for Light Detection and Ranging. This technology uses laser light to measure distances to a target by sending out pulses of light and recording the time it takes for the reflections to return. The principle relies on the speed of light, allowing precise calculations of distance based on the time delay between emission and reception of the light pulse. It is widely used in various fields such as surveying, geography, and speed measurement in law enforcement.

The other answer choices describe similar concepts but do not accurately define the term LIDAR. For instance, while some may mention “laser” or similar phrases, they do not capture the full scope of what LIDAR entails, particularly the role of light detection as a core component of the technology. Thus, the specified meaning of LIDAR as Light Detection and Ranging is essential for understanding its functionality and application.
