Abstract
An angle encoder, for measuring the angular position of a shaft, comprises at least two code carriers having correlated code indicia thereon, the two code carriers being coupled to the shaft for concurrent movement therewith past a scanning unit, and being so arranged that the relative position of the two code carriers changes successively during successive revolutions of the shaft. The two code carriers can comprise endless code tapes having different lengths, or mesh-engaged code disks having different sizes.
