Polarization effects in lattice–STED microscopy
Résumé
Massive parallelization of STED-like nanoscopies is now achievable using well-designed optical lattices for state depletion. Yet, only the lattice intensity distribution was considered for the description of the super-resolved point spread function. This
holds for fast-rotating fluorescent emitters. Here, we study the effects of electric field topography in lattice–STED microscopy. The dependence of the super-resolved point spread function on the number of dipoles and their orientation is
investigated. Single fluorescent nano-diamonds are imaged using different optical lattice configurations and the measured resolutions are compared to theoretical simulations.
