The time-of-flight laser scanner is similar to a radar.

It uses a flashing source of light instead of a radio beam.

Because of its characteristics of accuracy and distance range, it is especially suitable for architectural or geomorphologic survey.

The instrument developed by GBC, comprising a commercial range finder mounted on a system of motorised rotations, is suitable for application on site and permits distance surveys between 2-30 m with a quota resolution in the order of 1 cm at a typical speed of acquisition of 1.2. khz.
