Abstract
An angle-measurement device comprising a carrier element with at least two tracers. At least one tracer is configured as an annular surface, and at least one tracer is configured as a cylindrical surface. Each tracer has essentially coinciding periodic patterns that are electromagnetically or optically detectable by at least one sensor, and one tracer has a number N of patterns and the other tracer has a number N+1 of patterns. In another embodiment, one tracer is disposed on one face and the other tracer is disposed on another face of an annular carrier element.
