Class Projects
Intro and Overview
January 30, 2020
Developed by Katie Morzinski
Project in brief
1.
Choose an astronomy science
question that AO can help to answer
2.
Decide on an AO system that will best
address your science question
Slide 2
We are starting this class project
somewhat early in the quarter
•
A trade-off
•
If we wait till you know a great deal about AO,
the project ends up due at the end of the
quarter, the same time as all your other
projects and term papers
•
If we start now, you know less (so far) about
AO, but as the class proceeds you will be
able to connect the lectures to your project
Slide 3
Slide 4
Class project learning goals
•
Content Goals:
–
Using AO to achieve a specific
science goal
–
How to derive AO requirements
from science goal
–
Relation between image quality
and residual wavefront error
–
Understanding error budgets:
specific contributors; AO as a
system
•
Process Goals:
–
Systems thinking
–
Requirement-driven design
–
Optimization
–
Tradeoffs
Slide 5
What you will actually be doing during your project
1.
Choose collaborator(s) and a
general area of science
that
you are interested in using AO for
2.
Within your collaboration, come up with a
specific
“
science
case
”
(an investigable science question within your general
topic) that benefits from AO
3.
Decide upon specific
“
science requirements
”
needed in
order for a new AO system to address your science case
4.
Flow-down science requirements to performance
requirements for your AO system
5.
Given your performance requirements, design an AO system
(on paper) that meets these requirements
6.
Present your design to your peers in class (
“
Conceptual
Design Review
”
)
7.
Synthesis discussion of what we all learned from this process
Slide 6
Tentative schedule for class project
on AO System Design
•
Intro (today)
•
Starters (February 6th) in class
–
An example of how to choose key AO parameters
•
Focused Investigation (Feb 11th)
–
Group work during class time
•
First draft of Performance Requirements (Feb. 18th)
•
Rest of February: continue working together; move
from performance requirements to AO design, via
error budget
•
March 5
th
– “Conceptual Design Review”
–
Group presentations in class
•
March 10
th
– Project Synthesis
Slide 7
First tasks: Choose Collaborators, Science
Topic, Specific Science Case

1.
Today or by Feb 6
th
at the very latest
–
What broad science area are you interested in?
–
Who is (are) your collaborator(s) ?
–
Put Astro289 in subject line
1.
After end of class on Feb 11th (each group
together)
–
What specific science question do you want to
analyze?
–
How will AO help answer this question?
Slide 8
The process of using Adaptive Optics (AO) to achieve specific science goals, emphasizing requirement-driven design, optimization, and tradeoffs. Learn to derive AO requirements from science goals and design an AO system to meet performance requirements
