Issue Date: | 2018 | Volume: | Adaptive Optics Systems VI | Editors: | Close, Laird M.; Schreiber, Laura; Schmidt, Dirk | Series: | PROCEEDINGS OF SPIE | Number: | 10703 | First Page: | 1070335 | Abstract: | A future upgrade of the Keck II telescope's adaptive optics system will include a near-infrared pyramid wavefront sensor. It will benefit from low-noise infrared detector technology, specifically the avalanche photodiode array SAPHIRA (Leonardo). The system will either operate with a natural guide star in a single conjugated adaptive optics system, or using a laser guide star (LGS), with the pyramid working as a low-order sensor. We present a study of the pyramid sensor's performance via end-to-end simulations, including an analysis of calibration strategies. For LGS operation, we compare the pyramid to LIFT, a focal-plane sensor dedicated to low-order sensing. | Conference Name: | Adaptive Optics Systems VI | Conference Place: | Austin, Texas, United States | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/28314 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10703/2313190/Keck-II-adaptive-optics-upgrade--simulations-of-the-near/10.1117/12.2313190.short | ISSN: | 0277-786X | ISBN: | 9781510619593 9781510619609 |
