The subject of the invention is a device for the nondestructive recording of a rotational movement, e.g. of a probe, on the surface of a specimen. In a developed configuration, a translational movement on the surface of the specimen can be detected. To this end, the device comprises a transmitter which is set up to transmit a temporal sequence of excitation signals Si, which penetrate into the specimen at least to some extent and interact with it. Furthermore, an array is provided, which is based on a plurality of receivers which are set up to receive echo signals, which result from the interaction of the excitation signals Si, transmitted by the transmitter, with the specimen. The echo signals for an excitation signal Si which are absorbed by the receivers form a set M (Si) of measurement values. Finally, an evaluation unit is provided, which is set up to determine a rotational movement of the device on the surface from a plurality of measurement value sets M (Si) which are correlated with temporally sequential excitation signals Si.
