Functional Principle

The LiDAR sensor uses the principle of Pulse Ranging Technology (PRT). This

means the device measures the time between the emission of a light pulse and

the receipt of the pulse reflected by an object. Due to the constancy of the speed

of light, this time is a measurement of distance.

Compared with other distance measurement processes, runtime measurement is

affected very little by disturbances in the measuring environment. As a result, this

measurement process ensures a high level of accuracy even under tough

everyday industrial conditions. The light emitter and light receiver are located in

the rotating sensor head.
