AGW Sistema Adattivo di prima luce per LBT
ELTs a pplication of LBT AO components • Adaptive secondaries technologies to be used for • adaptive segments for ELTs. • Use of Pyramid WFS as co-phasing sensor for ELTs • segmented mirrors • Use of Pyramid sensor as High Order WFS > 100 subapertures • Use of LLL CCD in future ELTs AO system. Needs for • many pixels 256x256 and 1Kfps speed with low RON <1e- Fundings form European Community JRA1: High Order WFS comparison SH vs. Pyramid 260KE FP6 : Co-phasing sensor to test at VLT (APE experiment)
