Query: Developing Linear Dark-Field Control for Exoplanet Direct Imaging in the
  Laboratory and on Ground-based Telescopes   Imaging rocky planets in reflected light, a key focus of future NASA missions
and ELTs, requires advanced wavefront control to maintain a deep, temporally
correlated null of stellar halo at just several diffraction beam widths. We
discuss development of Linear Dark Field Control (LDFC) to achieve this aim. We
describe efforts to test spatial LDFC in a laboratory setting for the first
time, using the Ames Coronagraph Experiment (ACE) testbed. Our preliminary
results indicate that spatial LDFC is a promising method focal-plane wavefront
control method capable of maintaining a static dark hole, at least at contrasts
relevant for imaging mature planets with 30m-class telescopes.
