Query: Subdiffraction incoherent optical imaging via spatial-mode
  demultiplexing   I propose a spatial-mode demultiplexing (SPADE) measurement scheme for the
far-field imaging of spatially incoherent optical sources. For any object too
small to be resolved by direct imaging under the diffraction limit, I show that
SPADE can estimate its second or higher moments much more precisely than direct
imaging can fundamentally do in the presence of photon shot noise. I also prove
that SPADE can approach the optimal precision allowed by quantum mechanics in
estimating the location and scale parameters of a subdiffraction object.
Realizable with far-field linear optics and photon counting, SPADE is expected
to find applications in both fluorescence microscopy and astronomy.
