Helium Rough uses an advanced Dual Laser mapping technology for
cavity mapping.
The laser mapping model is constructed using shadow model and laser
mapping data from one laser. The dual laser mapping model is constructed
using shadow model and laser mapping data from two lasers. The diagrams
and movies for different types of scanning are demonstrated below.
Shadow model
Cavities of rough are not scanned in shadow model.
