Abstract

A calibration standard for geometry measurement calibration of a measurement system operating by tactile and/or optical means is provided which includes a flat surface having a structure that is capturable by a measurement system operating by optical and/or tactile means. The structure has a changeable periodicity that is capturable by a sensor in a first direction and/or in a second direction and for a change in the periodicity to code position information and/or direction information. In addition, a method for calibrating a coordinate measuring machine operating by tactile and/or optical means and to a coordinate measuring machine for such a method or having such a calibration standard is provided.
