Abstract:
A super-resolution optical imaging method and system, including: providing a periodic monolayer array of dielectric spheres or cylinders with a sufficiently small period such that the fields-of-view produced by the spheres or cylinders overlap providing an enlarged field-of-view; wherein the dielectric spheres or cylinders are fixed in their positions such that the array is adapted to be brought adjacent to a sample to be optically imaged as a whole; and applying pressure to the array to reduce a gap separating the dielectric spheres or cylinders from the sample to achieve super-resolution imaging with the enlarged field-of-view. The super-resolution optical imaging method and system further comprising positioning the dielectric spheres or cylinders adjacent to one another in the array by air suction through a periodic micro-hole array providing a monolayer arrangement with a negligible defect rate.
