In high spatial resolution imaging, a structure of a sample is marked with a substance selected from a group of substances capable of being repeatedly transferred out of a first state having first optical properties into a second state having second optical properties by means of an optical switch over signal, and capable of returning out of the second state into the first state, the two states differing in at least one criteria. Within areas the sample is transferred into the second state by means of the optical switch over signal with which at least one spatially limited area is purposefully omitted. An optical measurement signal is detected, which is associated with the substance in the first state and which comes out of a detection area including both the area omitted with the switch over signal and areas in which the substance has been transferred into to second state.
