When does LIDAR panning occur?

LIDAR panning refers to the technique where the laser beam is swung swiftly over a stationary object. This method allows for the collection of speed data over a broader area, capturing measurements from multiple angles as the beam sweeps across the target. By panning, the operator can ensure that the device tracks the object's speed effectively, enhancing the accuracy of the measurements taken.

In contrast, when the laser beam is stationary, it simply measures the distance to the target without any dynamic assessment of speed; therefore, this does not constitute panning. Aiming the beam at a moving object also does not imply panning, as it can mean that the laser is focused on a single point without sweeping across different positions. Lastly, turning the beam off even briefly doesn't involve any panning action, which is characterized by the movement of the laser beam across a target. Thus, the correct selection highlights the dynamic process involved in LIDAR speed detection.
