Millisecond focal plane telemetry is now becoming practical due to a newgeneration of near-IR detector arrays with sub-electron noise that are capableof kHz readout rates. Combining these data with those simultaneously availablefrom the wavefront sensing system allows the possibility of self-consistentlydetermining the optical aberrations (the cause of quasi-static speckles) andthe planetary image. This approach may be especially advantageous for findingplanets within about 3 $\lambda / D$ of the star where differential imaging isineffective. As shown in a recent article by the author (J. Opt. Soc. Am. A.,33, 712, 2016), one must account for unknown aberrations in severalnon-conjugate planes of the optical system, which, in turn, requires ability tocomputational propagate the field between these planes. These computations arelikely to be difficult to implement and expensive. Here, a far more convenientalternative based on empirical Green's functions is provided. It is shown thatthe empirical Green's function (EGF), which accounts for all multi-planar,non-common path aberrations, and results in a much more tractable and highlyparallel computational problem. It is also shown that the EGF can begeneralized to treat polarization, resulting in the empirical Green's tensor(EGT).
