Abstract
A scanning head for scanning a material measure on which markings with a period are formed periodically in the measuring direction includes at least two individual sensors configured to produce sensor signals by scanning the markings. The scanning head further includes a digital signal processing apparatus configured to produce at least one highly accurate output signal from the sensor signals. The scanning head is configured to output at least two different types of output signals. The at least two different types of output signals comprises at least one safe output signal and the at least one highly accurate output signal.
