Issue Date: | 2017 | Volume: | Adaptive Optics for Extremely Large Telescopes 5 (AO4ELT5) | Abstract: | The scientific potential of the ELT will rely on the performance of its AO systems that will require to be perfectly calibrated before and during the operations. The actual design of the ELT will provide a constraining environment for the calibration and new strategies have to be developed to overcome these constraints. This will be particularly true concerning the Interaction Matrix of the system with no calibration source upward M4 and moving elements in the telescope. After a brief presentation of the ELT specificities for the calibration, this communication focuses on the different strategies that have already been developed to get/measure the Interaction Matrix of the system, either based on synthetic models or using on-sky measurements. First tests of these methods have been done using numerical simulations for a simple AO system and a proposition for a calibration strategy of the ELT will be presented. | Conference Name: | Adaptive Optics for Extremely Large Telescopes 5 | Conference Place: | Tenerife, Canary Islands, Spain | Conference Date: | June 25-30, 2017 | URI: | http://hdl.handle.net/20.500.12386/32949 | URL: | http://research.iac.es/congreso/AO4ELT5/media/proceedings/proceeding-035.pdf http://research.iac.es/congreso/AO4ELT5/pages/proceeding0035.html |
