Abstract (en)

[origin: WO2013045210A2] The invention relates to a confocal sensor system (A) by means of which a focal point (BP) generated thereby is moved along a visual axis (4), orthogonal to the x, y plane of an x, y, z coordinate system, to a target z coordinate of a point (P) to be measured of a surface (7) to be measured of an object (B), wherein a light intensity (I(z)) of the light reflected by the surface (7), which is dependent on a distance of the focal point (BP) along the z axis to the point (P), is detected and is used in determining the actual z coordinate (Zp) of the point (P) by means of an evaluation device (21).
