Concept of detecting non-paraxial light fields. a Microscope system for tightly focusing tailored paraxial light fields and detecting fluorescence; b setup for the generation of tailored vectorial light fields with additional phase vortices (paraxial regime; SLM: spatial light modulator, L: lens, M: mirror, A: aperture, QWP1,2: quarter wave plate, CCD camera); c vectorial flower and d spider web structure (σ12 = ±8), whose polarization distribution is indicated black lines (red: flow lines), with according phase Φ12 of complex Stokes field Σ12
