摘要： The optical-fiber reference-value transmitter comprises an optical waveguide coil with at least one winding layer, within which the sections of the optical waveguide fiber between adjacent turns are of equal length. A pressure finger which is connected to a mechanical distance pickup is guided over the layer of the winding and in the process exerts a mechanical pressure on a comparatively narrow zone of the optical waveguide fiber of a turn, whereby a so-called microbending effect is generated in the waveguide fiber. An opto-electronic transmitting and receiving apparatus which is connected to the optical waveguide fiber determines the location of the pressure point caused by the pressure finger and thereby, the position of the pressure finger.
