DAG odak düzlemi araçları - hedefler ve seçenekler
(Türk Astronomi Derneği, 2020-12-11)
DAG projesi çerçevesinde, teleskobun da tanımlanması ve optiğinin belirlenmesinden sonra Türk Astronomisinin gereksinim ve gelecek hedefleri de gözetilerek proje ekibi DAG teleskobunun iki Nasmyth odağına yerleştirilecek ...
The effects of atmospheric turbulence on astrophysical observations
(Türk Astronomi Derneği, 2020-12-11)
Atmospheric turbulence is caused by random variations in temperature and pressure that spatially and temporally alter the air’s index of refraction. As electro-magnetic radiation from distant astronomical objects propagates ...
Adaptive optics for DAG telescope
(Türk Astronomi Derneği, 2020-12-11)
What we propose for DAG is therefore a natural guide star GLAO system, that can be turned into a highly efficient AO system. Thus the working principle and expected performance analysis will be shown. In this manner most ...
Observing with DAG: performance metrics of imaging and spectroscopy
(Türk Astronomi Derneği, 2020-12-11)
DAG telescope will be designed as a telescope with adaptive optics and seeing limited modes of observation. Its primary mirror will be a thin meniscus, controlled in shape by an active optics system. This implies specific ...
The DAG project and its management
(Türk Astronomi Derneği, 2020-12-11)
The DAG Project and managerial issues related to call for tenders, determination of technical specifications both for the telescope, the dome and the observatory building will be presented.
Adaptive backstepping approach for 2-DOF telescopes despite unknown wind disturbance
(Institute of Electrical and Electronics Engineers Inc., 2019-07)
Small ground telescopes on the marked are widely used in many space observatories and scientific researches. There are three main problems in such telescopes; positioning of the focal point and the need of tuning for both ...
The flexible adaptive optics concept
(Instituto de Astrofisica de Canarias, 2017)
The availability of small deformable mirrors with large number of actuators and stroke, on one hand, and versatile wavefront sensors (pyramid WFS), on the other, allows the development of AO systems whose equivalent pitch ...
