| الوصف: | Detection of scattered light can determine the susceptibility of dielectrics. Rayleigh criterion normally limits it: details finer than the wavelength of the incident light cannot be determined from the far-field domain. We show that putting the dielectric in motion (or time-modulating it) can be useful for determining its susceptibility. This inverse quantum optics problem is studied in two different versions: (i) A spatially and temporally modulated metamaterial, whose dielectric susceptibility is similar to moving dielectrics. (ii) A dielectric moving with a constant velocity, a problem we studied within relativistic optics. The vacuum contribution to the photodetection signal is non-zero due to the negative frequencies. Hence, certain susceptibility features can be determined without shining any incident field on the dielectric. This effect pertains to the far-field domain for (i), and to the near-field (but possibly long-range) domain for (ii). When the incident light is shined, the determination of dielectric susceptibility is enhanced for (i) and goes beyond the classical Rayleigh limit in the far-field domain. |
