Issue Date: | 2020 | Journal: | PROCEEDINGS OF SPIE | Volume: | Adaptive Optics Systems VII | Editors: | Schreiber, Laura; Schmidt, Dirk; Vernet, Elise | Number: | 11448 | First Page: | 194 | Abstract: | As the new generation of telescopes is coming soon, we need to solve or improve some issues related to the adaptive optics techniques, necessary to fully exploit their extraordinary capabilities in terms of sensitivity and resolution. The Ingot wavefront sensor was thought to overcome some limitations due to the use of artificial sources instead of natural ones: it is designed to cope with the typical elongation of Sodium Laser Guide stars that will be used by the ELTs. Here we present the preliminary tests we performed to properly set up an end-to-end simulator, in order to evaluate the performance of such a device. We describe the different configurations considered and the assumptions we made, discussing also some computational problems we faced building up the tool. We also show the results of the first simulations obtained closing the loop with a mock ELT telescope. | Conference Name: | Adaptive Optics Systems VII | Conference Place: | California, United States | Conference Date: | 14-18 December, 2020 | URI: | http://hdl.handle.net/20.500.12386/31219 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11448/2562190/Evaluating-the-performance-of-an-Ingot-wavefront-sensor-for-the/10.1117/12.2562190.full?SSO=1 https://api.elsevier.com/content/abstract/scopus_id/85100025661 |
