Acquisition (WBS 3.2.3.7)
PSF camera (WBS 3.2.3.12)
Atmospheric profiler (WBS 3.2.3.10)
AO diagnostics (WBS 3.2.3.9)

AO operational tools
• Acquisition: cameras to boresight science, TTFA, and LGS sources
• Diagnostics:
– Group of task related to AO quality assurance (QA)
– Assumptions: temperature, humidity, cleanliness, status
• These functions are part of AO enclosure and bench
• AO non real-time software
– Assumptions: AO telemetry data
• Part of AO real-time software

Acquisition camera
• Lead, Team: Chris Neyman
• Status:
– Conceptual design of the acquisition cameras including consideration of
the location and optical interface
– May need to revise/update when AO optical design is “frozen”
• To do:
– Finalize acquisition processing steps
– Write report
4
PSF Monitor Camera
• Lead, Team: Mathew Britton
• Status:
– Revised Requirements
– Draft report on feasibility
•
http://eraserhead.caltech.edu/keck/ngao/psf_camera/psf_camera.html
– Stopped worked on other WSPS elements
• To do:
– Complete report on feasibility of technique
• Collate with other design material as final report
5
Atmospheric Profiler
• Lead, Team: Chris Neyman
• Status:
– Requirements assuming current MASS/DIMM acceptable
– Acceptable for tomography and PSF recovery
• per discussion/emails with Gavel and Britton.
• To do:
– Write report
6
Proposed AO diagnostic systems
•
Integrated with AO (3.2.3.9)
– Radiometric calibration of instrument and AO focal planes
– Astrometric calibration source
– Point source simulator (NGS+LGS)
– Turbulence simulator
– Alignment and registration aides

•
Draft requirements for AO source simulator
Draft requirements turbulence simulator
Draft requirements for calibration lamps
No work on metrology system
To Do:
– Accuracy from wavefront error budget “calibration” allocation
– Complete interfaces with AO non RTC and RTC control systems
– Final Documentation
