Measuring segmented primary mirror WFE in the presence of vibration and thermal drift on the light-weighted JWST
2012
Space Telescopes and Instrumentation 2012: Optical, Infrared, and Millimeter Wave
The light-weighted design of the Optical Telescope Element (OTE) of the James Webb Telescope (JWST) leads to additional sensitivity to vibration from the ground -an important consideration to the measurement uncertainty of the wavefront error (WFE) in the primary mirror. Furthermore, segmentation of the primary mirror leads to rigid-body movements of segment areas in the WFE. The ground vibrations are minimized with modifications to the test facility, and by the architecture of the equipment
