Fergus did a set of demonstrations today for Oppenheimer, Brenner, and me of his planet-finding code for Oppenheimer's P1640 high dynamic-range imager. The imager blocks out most of the light of the star in an intermediate focal plane, but a combination of atmosphere and optical distortions plus physical optics means that still huge amounts of light hits the focal plane and in a very speckly pattern of blobs. Fergus showed us that he can (potentially) find planets among those speckles, even planets that are percent-level distortions of the speckle pattern! If this holds up it could have huge impact on high dynamic-range imaging, now and in the near future. For the past week or two I have also been playing around with modeling electromagnetic fields in imperfect cameras to see if we can make a more physically motivated model (Fergus's model is data-driven rather than physics-driven).
