What factor was highlighted in tests on LIDAR related to its accuracy?

• A. Angle of incidence
• B. Range
• C. Environmental conditions
• D. Refraction effects

Answer: (B)

The factor that was particularly highlighted in tests on LIDAR concerning its accuracy is the range. The range refers to the distance between the LIDAR device and the target object being measured. As the distance increases, the accuracy of the speed measurement can be affected due to various factors including signal spread and the potential for errors in how the device interprets the data from further away.

In practical terms, a LIDAR device operates optimally within a specific range, and deviations from that optimum range can introduce inaccuracies. For instance, if the target is too far away, the returned signal may not provide a clear or accurate measurement of speed. This is critical for law enforcement or any application relying on LIDAR for speed enforcement, as understanding this range can help ensure accurate readings are obtained and maintained during usage.
