Abstract
A position of a movable object is determined with a capture structure having a profile of an optical property that varies along a surface of the capture structure such that the profile corresponds to a progression of numerical values with local maxima and local minima on an ordered scale of the numerical values, and which is interpretable as a first mathematical function of the location. The optical property varies such that a second mathematical function of the location has an absolute maximum corresponding to a maximum value of the optical property. The optical property has assigned corresponding numerical values such that the progression thereof has the local maxima and the local minima and corresponds to the first mathematical function of the location. The position of the movable object is determined by a frequency analysis of the progression of the numerical values of the second mathematical function of the location.
