Two historians on a mission to preserve historic structures in Ethiopia inadvertently turned a cutting-edge 3D scanning device into a tool for creating works of art. Some lidar technologies can ...

While scanning, the laser shines across the target surface, and the reflected light is then picked up by the camera. So how does this $25 DIY laser scanner measure up? Great, to be honest.

Laser scanning, or Lidar, has been used for decades in fields like surveying, archaeology, and geology. The name, a portmanteau of "laser" and "radar," offers a rough sense of how it works: A ...

A tiny mirror, millimeters across, rotates along two axes, directing a fixed laser beam as it scans the scene. A second approach, known as flash lidar, dispenses with scanning altogether.

This 3D-printed confocal laser scanning microscope is a good example of an instrument for measuring really small stuff.

Researchers from the German universities of Würzburg and Potsdam have developed a new 3D laser scanner. This scanner helps ...
