Abstract
An optoelectric angle-measuring device has a code carrier having a position code which can be detected optically as well as a scanning device in the form of a light-sensitive row or area for detecting the position code and generating a position-dependent scanning signal. The scanning device which is in the form of a scanning film, in particular, surrounds the code carrier or the code carrier essentially completely surrounds the scanning device along a circumference. This provides an extremely accurate angle-measuring device by virtue of the fact that a large part of the position code, in particular even the entire position code, can be detected.
