ELT-scale adaptive optics real-time control with the Intel Xeon Phi Many Integrated Core Architecture (2018)
Journal Article
Jenkins, D. R., Basden, A., & Myers, R. M. (2018). ELT-scale adaptive optics real-time control with the Intel Xeon Phi Many Integrated Core Architecture. Monthly Notices of the Royal Astronomical Society, 478(3), 3149-3158. https://doi.org/10.1093/mnras/sty1310

We propose a solution to the increased computational demands of Extremely Large Telescope (ELT) scale adaptive optics (AO) real-time control with the Intel Xeon Phi Knights Landing (KNL) Many Integrated Core (MIC) Architecture. The computational dema... Read More about ELT-scale adaptive optics real-time control with the Intel Xeon Phi Many Integrated Core Architecture.

Calibration of quasi-static aberrations in high-contrast astronomical adaptive optics with a pupil-modulated point-diffraction interferometer (2018)
Journal Article
Dubost, N., Bharmal, N., & Myers, R. M. (2018). Calibration of quasi-static aberrations in high-contrast astronomical adaptive optics with a pupil-modulated point-diffraction interferometer. Optics Express, 26(9), 11068-11083. https://doi.org/10.1364/oe.26.011068

The direct detection and imaging of exoplanets requires the use of high-contrast adaptive optics (AO). In these systems quasi-static aberrations need to be highly corrected and calibrated. In order to achieve this, a high-sensitivity wavefront sensor...

Projected Pupil Plane Pattern: an alternative LGS wavefront sensing technique (2018)
Journal Article
Yang, H., Bharmal, N. A., & Myers, R. M. (2018). Projected Pupil Plane Pattern: an alternative LGS wavefront sensing technique. Monthly Notices of the Royal Astronomical Society, 477(4), 4443-4453. https://doi.org/10.1093/mnras/sty926

We have analysed and simulated a novel alternative Laser Guide Star (LGS) configuration termed Projected Pupil Plane Pattern (PPPP), including wavefront sensing and the reconstruction method. A key advantage of this method is that a collimated beam i... Read More about Projected Pupil Plane Pattern: an alternative LGS wavefront sensing technique.
