ABSTRACT:
A method for determining the absolute value of a rotational angle includes imaging a continuous segment of a code track of a code carrier on a sensor array such that the sensor array generates a corresponding output signal. The code track has a light and dark transition pattern over an angular range of 360°. The sensor array output signal is subjected to a convolution operation with a reference signal in a first correlation filter to reconstruct the light and dark transition pattern of the imaged segment of the code track as a first correlation function signal. The first correlation function signal is processed to determine a code word and a predetermined angle corresponding to the code word.
