Expérimental Description
Fluorescence lifetime is a powerful observable to probe local biochemical or electromagnetic environments. It carries information about molecular interactions (FRET, tension, pH…) but also about the local density of optical states (LDOS), a fundamental quantity in nanophotonics and quantum electrodynamics that governs spontaneous emission.
Super-resolution microscopy (Nobel Prize 2014) enabled the localization of single emitters with nanometric precision, yet lifetime information is still mainly acquired using cameras or confocal TCSPC, at the cost of speed, photon loss and limited multiplexing.
We are developing a new approach of dynamic illumination microscopy, where position, lifetime and spectral information of single-photon emitters are time-encoded in the illumination rather than in the emission image.
