A new concept of fluorescence microscopy is presented allowing the breaking of the diffraction limit of optical microscopy by a factor of ca. five. It relies on measuring the temporal evolution of fluorescence after sudden switch-on of the light excitation. The observed temporal dynamics of the fluorescence signal can be converted into information about the spatial distribution of fluorophores within the exciting laser focus. The proposed scheme is technically simple and versatile, and allows resolution enhancement in all three dimensions.
