Close loop correction of residual atmospheric dispersion in high-contrast imaging systems

[Abstract]
For direct imaging of habitable exoplanets from ground-based telescopes, it is crucial to correct for all the wavefront errors. One such error comes atmospheric refraction, in this talk, I will talk about why it is important to correct for refraction to the highest degree and how it can be achieved.
