Özet
In this article, we describe the current status of the development of TROIA* a pyramid wavefront sensor based adaptive optics system designed for DAG, a new 4 m telescope located in Eastern Anatolia, Turkey. The wavefront uses a no-noise electron-multiplied CCD camera, and the deformable mirror has a large actuators density, allowing coronagraphic science in one hand, but also system optimization for low light level or bad seeing conditions thanks to the versatility of the P-WFS. We describe the optical design, the mounting and alignment procedure and our loop control concept. Closed loop results are described, showing that while there are still many issues to fix before the sky version, the system behaves as expected.
Açıklama
The prism being used for V1 is the respectable prism that was a spare for the first ever P-WFS based AO system, installed on the Telescopio Nationale Galileo by the Italian P-WFS pioneer team. We once again express our gratefulness to Adriano Ghedina from TNG for giving us this precious prism.
