Abstract
A rotation angle sensor system for an optical system and/or a LIDAR system having a rotor and a stator for determining a rotation angle and/or an orientation between the rotor and the stator, which has a coil system that is stator-based and rotatably fixedly attached or attachable to the stator as a sensor element for receiving a magnetic alternating field, and, having a target that is rotor-based and rotatably fixedly attached or attachable to the rotor for generating a magnetic alternating field, and in which the coil system and the target are attached or are attachable to the stator and to the rotor so that different overlaps and/or spatial proximities occur between the coil system and the target as a function of the rotation angle and/or of the orientation between stator and rotor with a correspondingly different influence of the magnetic alternating field of the target on the coil system.
