Measurement of aspheric mirror segments using Fizeau interferometry with CGH correction
TL;DR: In this paper, a large aspheric primary mirror is used to measure concave segments with a Fizeau impedance interferometer where a spherical convex reference surface is held a few millimeters away from the mirror.

Modern technologies of fabrication and testing of large convex secondary mirrors
TL;DR: In this article, modern metrology systems including swing-arm optical coordinate measuring system (SOCMM) which is comparable to Interferometry and a Sub-aperture stitching interferometry scalable to a several meters have been presented.

TL;DR: In this article, the center reference fixtures have both a CGH and sphere mounted retroreflector (SMR) nests, which are aligned to the mirror's optical axis to provide a reference for mirror decenter.

Characterization of an alignment procedure using an air bearing and off-the-shelf optics
TL;DR: In this paper, the precision of five approaches used to align a series of targets over a distance of two meters is characterized. But, for systems with tight tolerances, we must have a measure of the uncertainties in the alignment telescope to determine if it can truly meet the system requirements.
