Traffic LIDAR utilizes which type of laser?

Traffic LIDAR systems primarily use semi-conductor lasers, which are known for their compactness, efficiency, and cost-effectiveness. These lasers are integrated into the LIDAR units to emit light pulses that are directed towards moving vehicles. The semi-conductor laser technology enables rapid modulation of the light, allowing for precise measurements of distance and speed by analyzing the time it takes for the laser light to return after reflecting off an object.

Semi-conductor lasers are favored in LIDAR applications because they are reliable and can operate effectively even in various environmental conditions. Their ability to produce narrow beams of light contributes to the accuracy of the distance measurements, making them ideal for use in traffic monitoring and enforcement.

Other types of lasers, such as solid-state, gas lasers, and fiber optic lasers, may have their respective applications in different fields but are not typically employed in traffic LIDAR systems due to factors such as size, application suitability, and efficiency in high-speed detection scenarios.
