A first grating is arranged at the first lateral surface with its grating lines parallel to the rotation axis, and a second grating is arranged at the second lateral surface with its grating lines parallel to said rotation axis.

摘要： Several photoelectric position measuring systems are described which utilize diffraction gratings to define the reference magnitude. Diffracted component beams are introduced by means of coupling-in gratings that have different grid constants from one another into optical waveguides to a coupler and there brought into interference. The interfering component beams are conducted from the outputs of the coupler via optical waveguides to detectors which transform them into electrical signals which are phase-shifted with respect to one another. Displacement of the diffraction grating is a measure for the position change to be measured of one machine component mounted for translation relative to another.
