Alignment of three mirror anastigmat telescopes using a multilayered stochastic parallel gradient descent algorithm
Solvay Blomquist, Heejoo Choi, Hyukmo Kang +4
When a telescope doesn't reach a reasonable point spread function on the detector or detectable wavefront quality after initial assembly, a coarse phase alignment on-sky is crucial…
