Abstract
A measuring device for determining a position and/or a speed includes a scale having marks arranged at spacings from one another, and a scanning head, with the scale and the scanning head being arranged for movement relative to one another along a movement direction. The scanning head is constructed to determine a first spacing of the scanning head in the movement direction relative to a first one of the marks, and a second spacing of the scanning head in the movement direction relative to a second one of the marks, with the position and/or the speed being determined on the basis of the first spacing and the second spacing.
