What deflection do we want? For Auxtel the FOV is about 6 arcmin. From center to side it's 2000*0.1 arcsec = 200 arcsec = 3.33 arcmin. So a deflection of 2 arcmin seems decent. If we're 4m away from primary, spot is displaced by only 2mm.
Problem with this config is beams are not very separated, spatially. We need a precision periscope on some to get more displacement.
Meghan Notes
- system will now have beam splitters
- do beamsplitter mapping
- look at alternatives and categorize
- clear a workspace
come up with plan and deadlines
SEMESTER PLAN:
- end of Jan - conceptual design review complete
- Tasks for Meghan
- make a 4-5 slide slide deck where I make pictures describing the system (include part numbers, make list)
- software architecture plan for controlling the mounts (can do during the lead time for hardware)
- read control manual for whatever mount setup we order
- If the adjustable hardware impeding timeline we abandon
- Place beamsplitter order and put below deadlines on calendar
- Tasks for Meghan
...
- Prototype one single collimated beam that we can steer around
- Optical source and control the light on/off (engineering milestones)
- Then, we scale this up to six steerable beams
- Then test these six beams on a telescope that we have HERE to test input (tight-beam demonstration)
- check in with telescope mounting after prof. stubbs trip (phone app that captures inside of telescope dome/Mario's Solidworks model)
