<p>The device (20) has a microscope (28) e.g. confocal microscope, or an optical sensor to determine the surface profile (21) of a cylindrical drilling (23) of a workpiece (26) e.g. engine cylinder (27). The microscope or the optical sensor is adjustable on the surface of the workpiece by an adjusting unit. Multiple positioning units (36) e.g. engines, move an objective (29), the microscope or the optical sensor in a radial or axial direction, and relative to the surface of the cylindrical drilling.</p> |
