1 Adaptive Optics Institute for Astronomy David Kim

2 Introduction Design Goals What is Adaptive Optics (AO) Hardware for AO Tests and Results

3 Design Goals Get Hardware Running Get Familiar With Hardware Design A Test Setup Link Hardware With Software

4 What Is AO? Deformable Mirror

5 Shack-Hartmann Wave front Sensor

6 Wavefront Sensor Data

7

8 Vector Display of wave frontVector Components

9 Boston Micromachines Deformable Mirror 140 Actuators MicroElectroMechanical Systems (MEMS)‏ Continuous or Segmented Deformable Mirror

10 Interferometer Test of BMC Mirror

11

12 Test giving left half actuators then right half 100 volts Interferometers Isometric plots of mirrors surface Expected to see half of the surface low and the other half high

13 Interferometer Test of Agile Mirror Identical Setup just a different mirror Left half and right half of actuators given 100 volts

14 Actuator Test of BMC Mirror

15

16

17 Conclusion Wavefront Sensor Operational Interferometer Setup Correct BMC deformable mirror broken New deformable mirror needed
