A device for optically scanning a surface is provided in the customary way with a projection device (4) for projecting a light beam (9, 12, 16) onto the surface (3) and a viewing device (5) for viewing the light (12) projected onto the surface at an angle to the projection device. To improve the scanning speed and accuracy and create a flexible all-purpose scanning device, the projection device (4) is provided with a mirror chip (10), e.g. of the DMD (digital micromirror device) type, for controlled deflection of the light beam (9). |
