Abstract:
1. A method for position determination comprising: generating a first position-dependent scanning signal and a second position-dependent scanning signal; transmitting said first position-dependent scanning signal from a scanning location via a first scanning channel to a first storage element; storing a first instantaneous value present at said first storage elements at a first storage time; transmitting said second position-dependent scanning signal from said scanning location via a second scanning channel to a second storage element; storing a second instantaneous value present at said second storage elements at a second storage time; forming a measured position value from said first stored instantaneous value and said second stored instantaneous value; wherein a first transit time of said first position-dependent scanning signal in said first scanning channel differs from a second transit time of said second position-dependent scanning signal in said second scanning channel, and said storing of said first instantaneous value and said storing of said second instantaneous value each takes place at times matched to said first and second transit times, respectively, so that each of said stored first and second instantaneous values are instantaneous values which have appeared at a common time at said scanning location.
