The 3D laser scanner is a system that scans the environment (in a quasi-spherical field of view) obtaining high-definition 3D model of the surrounding environment with a submillimetric resolution. The systems developed in ENEA are designed to withstand radiation, ultra-high vacuum and high magnetic fields and can be used at large distances for object detection with 1 meter accuracy. The development of the 3D laser scanner for Fusion Experimental Machines has led to the creation of many technologies and test that can find potential application across different non-fusion sectors including contactless metrology, inspection and quality control, long-range 3D image reconstruction, nuclear (non-fusion) environment and in obstacle avoidance 3D navigation systems.
