  2. Picture from Lab I

  3. The current test

  4. The Supervisor Software

  5. 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)

  6. PWFS The lab unit devoted to introduce A differential piston actuator for cube displacements Diff. Pist unit FISBA Reflecting surfaces of the cubes Co-Phasing Using Pyramid Sensor PWFS (2) assembly Aim of the set up is to measure at the same time a certain differential piston introduced using (3) with the two instrument FISBA (1) and PWFS (2). FISBA interf. Unit (1) Unit for (3) Differential piston

  7. Adaptive Secondary MMT Unit Pyramid WFS 1st Light AO 4 LBT
