Active Mirrors for High Contrast Imaging

Active Technology Project

Project Introduction

This effort is focused on implementing active primary mirrors for space-based telescopes.  Mirrors of this design have integrated electroactive actuators built into their lightweighted structure to allow for active wavefont correction during telescope operation.

The objective of this effort is to study the use of active primary mirrors for future space-based telescopes  Mirrors of this design have the potential to 1) achieve the necessary figure accuracy (~15 nm RMS surface) for UV/optical applications, 2) allow “cold” (35-40K) operation by correcting thermally induced figure changes, and 3) increase stability via active control and/or dynamic energy dissipation.  Considerations for operation at even deeper cryogenic temperatures (4K) have also been made for missions operating in the Far-IR regime (i.e. OST).  Techniques to measure these mirrors to ultra-precise levels are also under development.
