Solvay A. Blomquist, Sanchit Sabhlok, Hyukmo Kang +11
The Tiny Observatory for Telescope Optimization (TOTO) is an optical testbed designed to evaluate the efficacy of autonomously driven alignment algorithms for space-based telescope…
Stray and Scattered Light Considerations in a Non-contiguous Array of Commercial CMOS Sensors in a Space Mission
Maggie Y. Kautz, Douglas Kelly, Heejoo Choi +6
Recent advances in CMOS technology have potential to significantly increase the performance, at low-cost, of an astronomical space telescope. Arrays of sensors in space missions ar…
Stages of commissioning alignment for three-mirror anastigmat (TMA) telescopes
Solvay Blomquist, Heejoo Choi, Hyukmo Kang +7
Reliable, autonomously, deployment of telescopes enables a wide range of possible science cases. In this paper, we present a method for multi-stage telescope alignment with a simpl…
