Misalignment Induced Aberrations of JWST: Isolating Low Order Primary Figure Residuals from Misalignment
Abstract
It is important to isolate mirror shape accuracy from misalignment to maximize the ability to correct images in the James Webb Space Telescope. In this effort, nodal aberration theory was used to characterize the misalignment-induced aberration fields. This led to the discovery of a new misalignment-induced field dependence. A methodology has also been developed to integrate as-measured mirror figure errors characterized by a Zernike polynomial fit with nodal aberration theory.
