No need to modulate: On-sky results of a Neural Network enhanced pyramid wavefront sensor and prospects for the ELTs
Rico Landman, Liam Koning, Sebastiaan Y. Haffert +20
One of the main limitations of ground-based extreme adaptive optics systems (XAO) is the balance between the temporal and photon noise error. The unmodulated Pyramid Wavefront Sens…

The eXtreme Wavefront Control Toolkit: High-Contrast Imaging Instrument Control for Ground and Space-Based Coronagraphs
Jared R. Males, Joseph D. Long, Sebastiaan Y. Haffert +16
We present the eXtreme Wavefront Control Toolkit (XWCTk) instrument control software system developed for the MagAO-X extreme adaptive optics (ExAO) instrument. The XWCTk is built…
