Fisher information for far-field linear optical superresolution via homodyne or heterodyne detection in a higher-order local oscillator mode
Fan Yang, Ranjith Nair, Mankei Tsang +2
The distance between two point light sources is difficult to estimate if that distance is below the diffraction (Rayleigh's) resolution limit of the imaging device. A recently prop…

Interferometric superlocalization of two incoherent optical point sources
Ranjith Nair, Mankei Tsang
A novel interferometric method - SLIVER (Super Localization by Image inVERsion interferometry) - is proposed for estimating the separation of two incoherent point sources with a me…
