ADaptive Optics Near Infrared System (ADONIS) Fr.: ADaptive Optics Near Infrared System (ADONIS) An → adaptive optics instrument used on the → European Southern Observatory (ESO) 3.6-m telescope at La Silla. It was an upgraded version of COME-ON-PLUS, the → Very Large Telescope (VLT) adaptive optics prototype. It had 52 → actuators and performed corrections of the mirror 200 times per second. The reference → wavefront was sensed in the → visible. The observation was done in the → near-infrared (1-5 μm). → adaptive; → optics; → near-infrared; → system. |
