Summary:[Display omitted] •Our methods allow locating centimetre-sized objects with precision of the order of a micrometre.•The methods permit measuring displacements that take place over long periods of time.•The methods make it possible to monitor deformation of decimetre-sized objects. Two NMR data acquisition protocols together with corresponding data processing algorithms for locating macroscopic objects, measuring distances between them or monitoring their displacements or deformations with microscopic precision are presented and discussed. The performance of the methods is demonstrated by applying them to the measurement of deformations of a freely supported beam under loading. We believe that our methods will find their applications in mechanics, civil engineering and medicine.
