the collapse of Fisher information for estimating the separation of two close incoherent point sources by intensity imaging, which mode-sorting measurements avoid.

In metrology, Rayleigh's curse refers to the collapse of Fisher information for estimating the separation of two close incoherent point sources by intensity imaging, which mode-sorting measurements avoid. This meaning comes from Tsang (2016) in Physical Review X.[1]
