1. A field-modulating angular position measuring device, comprising:

  • a scanning device adapted to produce angle-dependent output signals;

    a measuring graduation, the scanning device and the measuring graduation arranged rotatably with respect to each other at a scanning distance;

    evaluation electronics adapted to process the output signals;

    a unit adapted to determine signal amplitudes of the output signals; and

    a temperature sensor adapted to determine a temperature in the angular position measuring device, the scanning distance determinable in accordance with the temperature and the signal amplitudes.
