Keskin, O., Jolissaint, L., Bouxin, A. & Yeşilyaprak, C. (2022). TROIA Adaptive optics system for DAG telescope; assembly and laboratory performance prior to on-sky assessment. Paper presented at the Adaptive Optics Systems VIII, 12185. doi:10.1117/12.2630893Özet
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.

Optical design of the adaptive optics system for DAG, the new 4 m Turkish telescope
Bouxin, Audrey; Jolissaint, Laurent; Keskin, Onur; Yeşilyaprak, Cahit; Spanò, Paolo (SPIE, 2020)We present the design of the Adaptive Optics System for the new Turkish 4-m telescope (DAG). The AO will use a pyramid WFS, with a double prism and a no noise EM-CCD camera to allow for oversampling of the pupil images and ... -
On complex solutions of the eikonal equation
Hasanoğlu, Elman (IEEE, 2007)In this paper a new approach of complex rays in an inhomogeneous medium is presented. Complex rays are complex solutions of the eikonal equation, the main equation of the geometical optics. It is shown that solving the ...
