Rotation angle transmitter and method of scanning a code disc of a rotation angle transmitter |
摘要 |
An optical rotation angle transmitter includes a code disc that has a digital coding and an analog coding. The digital coding has multiple tracks and is configured so as to be secure against error. A current angle interval can be determined from a plurality of possible angle intervals by means of the digital coding, and a precise angle position of the code disc can be determined within the current angle interval by means of the analog coding. Each of the tracks of the digital coding has a light sensor associated with it. Further provided is a method of scanning a code disc of a rotation angle transmitter.
