Long exposure image of a Roman silver spoon being laser scanned at the British Museum

Normally only visible to the naked eye as a single line, this long exposure image captures the path of the laser as it passes over the spoon’s surface. Scanning highly reflective surfaces such as this polished spoon is difficult, as most of the laser light is reflected away from the camera, so many points cannot be measured. However, passing the laser over the same area multiple times and from different directions, it’s possible to gather enough measured points to create a very accurate model of the objects surface.
