Detection of scattered light can determine the susceptibility dielectrics. Such imaging normally holds Rayleigh's limit: details finer than wavelength incident cannot be determined from far-field zone. We show that time -modulation an inhomogeneous dielectric used to its susceptibility. To this end, we focus on inverse quantum optics problem for spatially and temporally modulated metamaterial, whose is similar moving vacuum contribution photodetection signal nonzero due negative frequencies...
We study an inverse scattering problem in which the far-field spectral cross-correlation functions of scattered fields are used to determine unknown dielectric susceptibility object. One-photon states for incident field can resolve (at $100\%$ visibility) twice more Fourier components compared (naive) Rayleigh estimate, provided that measurement is performed back-scattering regime. Coherent not capable reaching this optimal resolution (or do so with negligible visibility). Using two-photon...
