Abstract

A rotation angle sensor system for an optical system that includes a rotor and a stator, includes a stator-based coil system having an inductance and for generating and transmitting a magnetic alternating field, and a rotor-based target that functions as an eddy current element for receiving the magnetic alternating field and generating a magnetic eddy current field. The coil system and the target are mounted or mountable fixedly, with respect to rotation, on the stator and the rotor, respectively, in such a way that different overlaps and/or spatial proximities between the coil system and the target, with correspondingly different effects on the magnetic alternating field of the coil system, result as a function of the rotation angle and/or of the orientation between the stator and the rotor.
