What class of LASER does LIDAR belong to?

• A. Class 3
• B. Class 2
• C. Class 1
• D. Class 4

Answer: (C)

LIDAR (Light Detection and Ranging) systems typically operate using a Class 1 laser. This classification indicates that the laser is considered safe under all conditions of normal use, which means it does not pose a risk to eye safety. Class 1 lasers are designed to not emit sufficient power to cause injury, making them ideal for applications where prolonged exposure might occur, such as in speed measurement devices for law enforcement.

In contrast, other classes of lasers have different safety implications; for example, Class 2 lasers emit visible light and can cause eye damage if viewed directly for extended periods, while Class 3 lasers can be hazardous under certain conditions. Class 4 lasers, the highest classification, can cause serious eye and skin injury and require strict safety precautions. Therefore, identifying LIDAR as a Class 1 laser emphasizes its safety features in regular operation, which is vital for its functionality in measuring speed without posing a threat to users or the public.
