Advanced adaptive optics (AO) instruments on ground-based telescopes require accurate knowledge of the atmospheric turbulence strength as a function of altitude. This information assists point spread function reconstruction, AO temporal control techn...

Phase A AO system design and performance for MOSAIC at the ELT (2018)
Presentation / Conference Contribution
Morris, T., Basden, A., Calcines-Rosario, A., Dohlen, K., Dubbeldam, C., El Hadi, K., Fitzsimons, E., Fusco, T., Gendron, É., Hammer, F., Jagourel, P., Jenkins, D., Morel, C., Morris, S., Rousset, G., Townson, M., Vola, P., & Younger, E. (2018, June). Phase A AO system design and performance for MOSAIC at the ELT. Presented at Adaptive Optics Systems VI: SPIE Astronomical Telescopes + Instrumentation 2018, Austin, Texas

MOSAIC is a mixed-mode multiple object spectrograph planned for the ELT that uses a tiled focal plane to support a variety of observing modes. The MOSAIC AO system uses 4 LGS WFS and up to 4 NGS WFS positioned anywhere within the full 10 arcminute EL... Read More about Phase A AO system design and performance for MOSAIC at the ELT.

ELT-scale adaptive optics real-time control with the Intel Xeon Phi Many Integrated Core Architecture (2018)
Journal Article
