Which technology utilizes laser light for distance measurements?

LIDAR, which stands for Light Detection and Ranging, specifically uses laser light to measure distances. The technology works by emitting laser pulses and measuring the time it takes for the light to reflect off objects and return to the sensor. This time-of-flight measurement allows for precise distance calculations. LIDAR is commonly used in various applications such as topography, forestry, and autonomous vehicles, making it a versatile tool for creating detailed three-dimensional maps and models.

In contrast, RADAR uses radio waves instead of laser light to detect objects and measure distances. Sonar operates with sound waves and is primarily used underwater for navigation and object detection. Infrared sensors rely on infrared light, which is typically used for detecting thermal signatures rather than distance measurements directly. Each technology has its own specific application domain, but LIDAR distinctly differentiates itself by leveraging laser technology for its distance measurements.
