Files and Notes for 2014_08_13 Meeting


Yesterday we got the beacon from the scope to the Lab-AO WFS:
2014_08_12_LABAO_Beacon_YSO_200Hz_X0.05_Y0.02_noboxes.png
The four spots on the right are all there but faint due to the lower periscope obscuration.

Things we should talk about:

1. What is the dumb factor of 2 I am missing in the math?
2. How far apart should the WFS unit be form the lens? How do we best align this? Note that we now have about 13.5 pixels between spots.
3. Is the DM working as well as we would like? Should we buy more parts?
4. The WFS is proving to be a great aid in alignment.
5. How exactly is the WFS unit put together. The focus is for between the lenslet and the camera right?
6. The seems to be enough light coming form the beacon in YSO mode, although more would be nice.
7. We need computer controlled micrometers on the WFS on the scope.
8. There is a lot of clean up work to do on scope WFS code.
9. Plan to try using both systems together Thursday night.
10. Camera link is working in test program but not in thread…. which I do not understand.
11. Automated control of dichroic at scope to keep systems co-aligned is coming soon.
12. What is the status of the remaining WFS?
13. What is the status of the table installation?
14. What is the status of the dichroic shifters?
15. What is the status of the quotes for DM's?
16. We need to be able to add low order offsets to the LAB-AO WFS output so we can correct for scope problems as detected by the scope WFS.
