Spatial-mode-sorting (SPADE) receivers surpass Rayleigh’s criterion for incoherent imaging but are sensitive to nuisance parameters (e.g., misalignment). Our multistage detection strategy uses preliminary physical measurement(s) to build up required prior information for near-quantum-optimal, sub-diffraction imaging.
