Which of the following is a characteristic of Lidar technology?

• A. Uses analog signals for transmission
• B. Requires extensive radar calibration
• C. Operates using light for measurement
• D. Functions exclusively outdoors

Answer: (C)

Lidar, which stands for Light Detection and Ranging, operates by emitting light pulses and measuring the time it takes for those pulses to bounce back after hitting an object. This characteristic allows it to determine distance, speed, and other relevant data based on the light signals. Unlike traditional radar, which utilizes radio waves, Lidar utilizes visible, ultraviolet, or near-infrared light. This unique mechanism is essential for its precision and effectiveness in speed measurement and other applications.

The other options do not accurately describe Lidar technology. For instance, it does not use analog signals for transmission but rather digital technology to calculate distances and speeds. While radar calibration might be necessary for radar devices, Lidar has its calibration methods that do not require extensive radar-specific adjustments. Lastly, Lidar can function in various environments, not limited to outdoor settings, as it can also be utilized in some indoor applications where light conditions permit.
