The ancestor of the 3D vision glasses that allow us to see through the walls already exists! A much larger and less portable version is available in the form of the 3D Tomograph. Indeed, this equipment allows us to reconstruct the interior of a room in 3D and to be able to move it in space, so to look at it from every angle and to find the potential defect. A very useful device when the problematic part is the only one we have, and we do not want to deal with destructive analysis techniques. A beautiful combination of the glasses of our superheroes of yesteryear and glasses of virtual reality today!
