In　this　paper,　we　propose　a　promising　super-resolution　imaging　scheme　in　fluorescence　lifetime　domain　(lifetime　super-resolution　optical　fluctuation　imaging,　ltSOFI).　ltSOFI　has　the　potential　to　obtain　super-resolution　images　by　taking　advantage　of　fluorescence　lifetime　blinking　under　wide-field　lifetime　detection.　The　proof-of-concept　for　ltSOFI　was　demonstrated　through　numerical　simulation　of　high-order　cumulant　analysis　on　fluorescence　lifetime　blinking　emitters.　As　a　tentative　experimental　demonstration,　we　obtained　super-resolution　lifetime　imaging　from　time-lapse　FLIM　recording　of　HeLa　cells　expressing　a　cAMP　sensor　using　ltSOFI　method.　ltSOFI　is　expected　to　initiate　a　new　dimension　in　the　lifetime　domain　for　blinking-based　super-resolution　microscopy.
