<p>Disclosed is a 3D scanner for recording the 3D topography of an object, the 3D scanner comprising:
- an illumination unit configured for providing probe light for illuminating the object, where the probe light comprises a pattern of light rays;
- an image sensor for acquiring one or more 2D images of light rays returning from the illuminated object;
- an optical system comprising an optical element arranged such that the patterned probe light passes through it when propagating towards the object from the illumination unit along an optical path; and
- a device for changing the configuration of the optical system between a first and a second configuration, where the change in configuration comprises a change in orientation of the optical element between a first orientation and a second orientation relative to the optical path of the probe light such that the change of configuration provides a shift in the position of the probe light pattern on the illuminated object.</p> |
