Abstract
The invention relates to an optoelectronic angle sensor () for determining a rotational angle about an axis (), comprising a circular disk () that can be rotated about the axis. Said circular disk comprises a coding, essentially over the entire surface, a flat photosensitive detector (), a device for producing an evaluable image of the coding on the detector and a memory and evaluation component () for determining the rotational angle. A largely complete, or in particular an entire image of the coding is produced on the detector. The rotational angle is determined using a parameter-varying stochastic comparison method, from the image and a parameterised electronic reference pattern that is provided by means of the memory and evaluation component.
