| 中文摘要 | LINC-NIRVANA is a near infrared interferometric imager with a pair of layer-oriented multi-conjugate adaptive optics systems (ground layer and high layer) for the Large Binocular Telescope. To prepare for the commissioning of LINC-NIRVANA, we have integrated the high layer wavefront sensor and its associated deformable mirror (a Xinetics-349) in a laboratory, located at Max Planck Institute for Astronomy, in Heidelberg, Germany. Together with a telescope simulator, which includes a rotating field and phase screens that introduce the effects of the atmosphere, we tested the acquisition of multiple guide stars, calibrating the system with the push-pull method, and characterizing the wavefront sensor together with the deformable mirror. We have closed the AO loop with up to 200 Zernike modes and with multiple guide stars. The AO correction demonstrated that uniform correction can be achieved in a large field of view. We report the current status and results of the experiment. © 2012 SPIE. |
