Abstract:
1. 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 the optical element 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.
