Abstract:
Device for measuring structures of an object by means of a stylus (10) assigned to a coordinate measuring device (22) and comprising a stylus element (12) and a stylus prolongation (14) in the form of an optical waveguide, wherein the coordinate measuring device (22) comprises a sensor for the optical determination of the stylus element (12) and/or at least a target marker assigned directly to the stylus element, and an evaluation unit, with which the structure of the object can be calculated from the position of the optical sensor in relation to the coordinate system of the coordinate measuring device and the position of the stylus element or the target marker, measured directly by means of the optical sensor, characterized in that the sensor forms a jointly adjustable unit with the stylus; in that the stylus (10) is connected via an optocmechanical interface (28, 34) to an adjustment device (24) in the interchangeable support (16), wherein the adjustment device can be adjusted in relation to or with the interchangeable support, rotationally and linearly; in that the stylus is connected to the optomechanical interface such that the stylus can be exchanged; and in that the interchangeable support is connected magnetically and mechanically to a support (20) that is connected to the sensor.
