The circular disk which the photoelectron angular sensor and that measuring method null axis which measure the turning angle

摘要

Optoelectronic angle sensor that measures the rotation angle axis (6) around the invention relates to (1a). The optoelectronic angle sensor comprises a circular disc rotatable about said axis (2a). The circular disk, the entire surface has been encoded. The circular disk includes a device detector plane photosensitive and (3a), and generates the detector encoded images can be calculated, memory computational elements for measuring a rotation angle, and (4a) there. Image, in particular, the entire image is generated to the detector most of encoded. Said image, and the rotation angle is measured using a parameter variation probability comparison method of electronic reference pattern parameterized provided by the memory element calculation.
