Nanophotonics for optical super resolution from an information theoretical perspective: a review

摘要

Optical super resolution is one of the most applicable as well as scientifically exciting field of optics dealing with imaging and aiming to improve the spatial resolvable capabilities of any imaging system (digital or ophthalmic) without modifying the optical parameters of the imaging lenses or the geometry of the detection array. Recent developments in nanotechnological fabrication capabilities open new doors of possibilities in fulfilling modified and improved super resolving configurations. Fundamental concepts for obtaining super resolved imaging are related with time, angular, wavelength, polarization and gray levels multiplexing. The state of the art in the field of optical super resolution is reviewed while showing its relation with nanophotonics.
