Polarimetric imaging with high spatial resolution [PDF]

Scientific Reports
Despite its critical importance in many biomedical devices, the polarization of light is often neglected or considered as a problem to be contained. The reason is related to considerable challenges to measure it. In the present work, a simple motion-free

Spatial spectroscopy for high resolution imaging [PDF]

EPJ Web of Conferences, 2020
Quantum estimation theory provides bounds for the precision in the estimation of a set of parameters that characterize a system. Two questions naturally arise: Is any of these bounds tight?
