WebbThis study reviews the fundamentals and the recent progress of the small focal spot formation by vector beams. Some advanced features, including superoscillation … WebbA simple, stable and cheap method allowing the generation of beams of any polarization and more especially of purely radially polarized light beams is proposed and demonstrated both theoretically and experimentally that for near‐field imaging systems polarization is a limiting factor of resolution and light confinement. 51 follow up email after networking call
Super-Oscillation by Higher-Order Radially Polarized Laguerre
Webb15 feb. 2024 · We investigate the focusing properties of cylindrical vector beams (CVBs) generated from the combination of an array of beams, each with sub-apertures and controllable polarization. The analytical expression of the tight focusing field of the combined CVBs has been derived based on the Richard-Wolf vector diffraction integral.

A 4-f system (Lens 1 and 2 in Fig. 1) re-images the produced beam vector fields into the 10 mm input aperture of a scanning galvo (Nutfield). At the galvo output, the beam is focused with a flat field f-theta lens (f = eight ball toy
