In the context of exoplanet imaging with current/future ground/space-based telescopes, we developed the THD2 bench for testing high contrast imaging solutions in visible/near-infrared at 10-9-10-8 contrast levels :

  • Coronagraph component characterization
  • Pupil apodizer characterization
  • Focal plane wavefront sensor comparison
  • Post-processing for speckle minimization
