Measuring dimensions is something that comes natural to a laser, especially if we are talking about small distances. Inside a room, a good laser system can determine everything there is to determine in a manner of seconds. But the main issue plaguing these systems has until now been the fact that they did not operate... |

People usually take many things for granted, including the ability to always appear in motion in a static world. The human brain is able to receive constant updates from all its sensors – eyes, ears, skin, nose and so on – and then update our position in real-time. When this happens cursively, we understa... |
