Resolution is the ability of a measuring machine to distinguish small quantitative differences in a physical quantity (e.g. length, current). In coordinate metrology, structural resolution and spatial resolution are important and must be carefully distinguished: The structural resolution of a coordinate measuring machine describes the smallest possible size of structures (object features such as bores and radii) that can still be captured (sampling theorem) and measured (sufficient number of points per feature) separately from other neighbouring structures. In contrast, the spatial resolution of the coordinate measuring machine describes the smallest measurable spatial difference between the measurement points. Both parameters have an effect on the characteristics and the measurement uncertainty when using coordinate measuring machines. However, as explained in the following sections, these are influenced by many other factors.
