Abstract
A method for position determination that includes generating first and second position-dependent scanning signals, transmitting the first and second position-dependent scanning signals from a scanning location via corresponding first and second scanning channels to corresponding first and second storage elements, storing corresponding first and second instantaneous values present at the first and second storage elements at corresponding first and second storage times. Forming a measured position value from the first stored instantaneous value and the second stored instantaneous value. A difference exists between corresponding first and second transit times of the first and second position-dependent scanning signals in the corresponding first and second scanning channels, the difference is compensated by individually delaying the first and second position-dependent scanning signals, so that the stored first and second instantaneous values have appeared at a common time at the scanning location.
