 LGSWFS meeting

1-day meeting on LGSWFS for E-ELT instruments, with the principal actors :



Contacts :
Benoit Neichel
Thierry FUSCO


Rationale

The goal of this first meeting is to bring different actors in the same room, and understand if there are things that could be shared between the different projects.

There are potentially many simulations that could be spread over the institutes, and save time/resources for all. For instance, what is the impact with the NGSD 800x800 pixels. This is suboptimal if we want to do the full SHWFS and means either work with truncated spots, or undersampled spots, or use alternative optical solutions to shrink the spots or consider pyramids. Another example are the zoom systems, could we find a common solution for all LGS instruments ?

Local Information

Take the Metro Line number 1 until the terminus "La Rose".
Go out of the metro station, turn right at the bottom of the electric stairs, and go to the bus station at 20m in front.
Take the bus B3B, it is a long bus, and leave it after 2 stations, at the "Technopole Centrale Marseille" LAM is just in front, a little bit toward your left.

As we have several connections from outside, the easiest setup is to use Renavisio. Which means that YOU will have to start the connection.
