Summary
[edit]DescriptionJWST Segment Alignment.gif |
English: Segment Alignment
After we have the image array, we can perform Segment Alignment, which corrects most of the large positioning errors of the mirror segments. We begin by defocusing the segment images by moving the secondary mirror slightly. Mathematical analysis, called Phase Retrieval, is applied to the defocused images to determine the precise positioning errors of the segments. Adjustments of the segments then result in 18 well-corrected “telescopes.” However, the segments still don’t work together as a single mirror. |
