Germany’s Fraunhofer Institute for Applied Optics and Precision Engineering has created a scanner that replaces the lasers of typical 3D scanners by using a pattern of infrared light. The measuring technology works in a similar way to human vision, but uses two near-infrared cameras instead of eyes. Infrared rays are invisible to the human eye, so the scanner measures the surface invisibly with high accuracy. This makes it possible to create high-resolution 3D images of 1,000 x 1,000 pixels at 36 3D images per second. The system is able to create images continuously without a break, creating the impression of…
