On March 3, 2021 in Tucson AZ, AOS successfully demonstrated the metrology system they have built to measure the aspheric prescription of the 91色情片 primary mirror segments. This test set uses a full-aperture reference surface and a Fizeau interferometer to measure the curvature of the off-axis segments. This test set will guide the Ion Beam Figuring process which will bring the 91色情片 segments to their final surface figure requirements.
