Abstract
The present invention relates to a method and apparatus for determining an absolute angle and torque with an optical detection module, in which the absolute angle and the torque are determined on the basis of measurements including marked waveforms at both ends of a torsion bar, relative rotation angles at both ends of the torsion bar, and revolutions per minute of the torsion bar measured with the aid of the revolution number measurement unit.
