Abstract
An active tilt mirror mechanism, meant for correction of the constellation breathing of the evolved Laser Interferometer Space Antenna, has been designed and realized. Its open-loop performance has been characterized in both time and frequency domain. Based on this, a feedback controller has been designed and the resulting closed-loop performance has been assessed. Up to what is measurable in a normal lab environment, these experiments demonstrate compliance with the extreme pointing jitter requirement, even when using the internal encoder as feedback sensor.
