Hi Axel,
Thanks for sharing the slides! A new variation around the sequential phase diversity / fast&furious concept, now using reinforcement learning, should be added to your list: https://arxiv.org/abs/2604.00993
I guess Jalo will be talking about that during our next meeting. The accepted paper only presents wavefront flattening, but FYI Jalo has already been able to dig dark holes with the same framework, by ‘just’ changing the reward.
Regarding the asymmetric pupil WFS, you may want to add a ref to the Asymmetric Lyot Wavefront sensor (Orban de Xivry+2024), which shows that the concept can be extended to focal-plane phase mask coronagraphs.
Cheers,
Olivier

Dear PCS WP2 member,
I propose you to postpone our next meeting WP2.3 (wavefront sensing and control) that was originally planned tomorrow.
Here is the new time slot: April 24th from 10am to 11am. I will ask some of you to present their current projects, followed by a discussion on the next steps.
Meanwhile, you can find attached the literature review we have discussed the past few months. This is still a draft and I know I still miss a few information some of you already provided. So please reach out to me for any update or correction on the current draft :-) .
Have a great end of the week,
Best,
Axel
