LIDAR 101

What is lidar?

Lidar (li ght d etection a nd ranging) uses eye-safe laser beams to "see" the world in 3D, providing machines and computers an accurate representation of the surveyed environment.

How Does Lidar Work?

• A typical lidar sensor emits pulsed light waves into the surrounding environment.

  

• These pulses bounce off surrounding objects and return to the sensor.

  

• The sensor uses the time it took for each pulse to return to the sensor to calculate the distance it traveled.

  

Repeating this process millions of times per second creates a precise, real-time 3D map of the environment. This 3D map is called a point cloud. An onboard computer can utilize the lidar point cloud for safe navigation.
