Abstract

Scanning system for scanning the surface (13, 14) of an object, in particular for a coordinates measurement machine. A scan sensor (1) comprises at least one fluid-mounted light transport module (2), a fluid being located between the light transport module (2) and a bearing part (3) in a bearing gap (7), by means of which fluid the light transport module (2) is mounted in such a manner that it is movable both axially and also rotating in relation to the axis of the cylindrical external wall. Primary light originating from a light source is transported through the interior (8) of the light transport module (2) to a primary exit point (12a, 12b) distal in the axial direction, from which it is emitted in the direction toward the object surface (13, 14). Secondary light reflected from the object surface (13, 14) is also transported through the interior (8) of the light transport module (2) to a secondary light exit point (17) distal in the axial direction from the secondary light entry point (16a, 16b). The light transport module is drivable both in the axial direction and also rotating by means of a rotation-translation drive (27).
