摘要：device for measuring small lengths, with a in the direction of the measuredlength of tastspitze movable with a converter for converting the movement of thetastspitze into corresponding electrical signals, and a anzeigeein\­richtung todisplay the signals.the converter includes an optical interferometer, which has a

me\ßwellenleiter whose one end with a laser and the other end is connected with anoptical device, the light in a distance from me\ßspiegel is the light to the opticaleinric farming back. the me\ßspiegel is associated with the tastspitze.moreover, theinterfero\­meter a bezugswellenleiter, with the me\ßwellenleiter is coupled atone end and a mirror and at the other end of a lichtelektrischen transducer which, withthe indicating device to display the electric ausgangssignals of e lektrischen transformeris connected.the device can be inexpensively and simply as opto\­elektrischeintegrated unit training. it allows a measurement with a precision of the order of half thewavelength of light of the laser or far below even at great lengths to be measured withhigh linearity.the device is for measuring very fast l\ängen\ände\­rungensmall auflagedr\ücken the tastspitze suitable.
