Focus diverse phase retrieval test results on broadband continuous wavefront sensing in space telescope applications
Hyukmo Kang, Kyle Van Gorkom, Meghdoot Biswas +2
Continuous wavefront sensing benefits space observatories in on-orbit optical performance maintenance. To measure the phase of a wavefront, phase retrieval is an attractive techniq…

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…
