Opto-electrical angle measuring apparatus

摘要

The device has a code carrier carrying a position code (C1), where a scanning foil (F1) is in the form of a light-sensitive row or area for detecting the position code (Cl) and generating a position-dependent scanning signal. The scanning signal is associated with an angle between the code carrier and the scanning foil. The scanning foil completely surrounds the code carrier or the code carrier completely surrounds the scanning foil along the circumference.
