Abstract
A device for the tactile determination of a surface shape of a measuring object includes a micro probe arm having a stylus tip, the micro probe arm being fastened on an optical fiber having a fiber end, which is mounted in a probe housing, a reference mirror is provided in the probe housing, and an optical measuring device is provided for determining the position of the fiber end in relation to the reference mirror. The contactless interferometric determination of the distance between the fiber end of the optical fiber and the reference mirror attached in the probe housing allows precise determination of the surface shape of the measuring object.
