Fig. 11: Superoscillation optical field characterization systems.
From: Superoscillation: from physics to optical applications
a The superoscillatory fields are obtained by a high-NA microscope with an objective lens mounted on a 1D nanopositioner (1D NP), where the camera is used to obtain the 2D intensity distribution of the diffraction pattern. b A testing system based on a tapered nanofibre probe (TNFP) mounted on a 3D nanopositioner (3D NP), where a single photon counter (SPC) is used to detect the weak optical signal from the nanofibre probe
