Flight Qualification and Performance Testing of SIM Precision OpticalMechanisms

摘要

The SIM-Lite project has designed and built PZT driven precision optical mechanisms for pointing and optical path-length phasing. This paper will discuss the designs, the flight qualification, and performance in a space representative environment of these dynamic optical devices. We will also discuss performance of the strain gauges bonded to the PZTs of the SIM Fine Steering Mirror.
