Abstract
Super-resolution in optical imaging refers to approaches that can boost spatial resolution beyond the diffraction limit. One approach to achieving super-resolution is the super-growth phenomenon. In supergrowing fields, the local growth rates can be faster than that dictated by the fastest Fourier component. Our initial investigations suggest that supergrowth is more sensitive than super-oscillation for attaining super-resolution. We present experimental synthesis and characterization of supergrowing fields in the laboratory—a critical step towards achieving super-resolution. This experimental demonstration will assist in determining the optimal super-growing fields that are realizable in the lab and can be utilized for super-resolution imaging.
