| Outline of Final Research Achievements |
We aimed to explore super-resolution imaging with confocal optics by super oscillation of a vector beam, which generates a much smaller spot than diffraction limit. By focusing a multi-ring structured, radialy polarized beam generated by a liquid crystal device, fluorescence or scattering images were acquired. A small spot corresponding to quarter of the wavelength was formed and used for the imaging of aggregated 170 nm fluorescent beads, which were clearly distinguished with each other. Eventually, higher resolution breaking the limit of conventional optical microscopy was accomplished.
