Design of pre-optics for laser guide star wavefront sensor for the ELT
Eduard Muslimov, Kjetil Dohlen, Benoit Neichel +1
In the present paper, we consider the optical design of a zoom system for the active refocusing in laser guide star wavefront sensors. The system is designed according to the speci…
A fast, wide-field and distortion-free telescope with curved detectors for surveys at ultra-low surface brightness
Eduard Muslimov, David Valls-Gabaud, Gérard Lemaître +6
We present the design of an all-reflective, bi-folded Schmidt telescope aimed at surveys of extended astronomical objects with extremely-low surface brightness. The design leads to…
Combining freeform optics and curved detectors for wide field imaging: a polynomial approach over squared aperture
Eduard Muslimov, Emmanuel Hugot, Wilfried Jahn +5
In the recent years a significant progress was achieved in the field of design and fabrication of optical systems based on freeform optical surfaces. They provide a possibility to…
Combined narrowband imager-spectrograph with volume-phase holographic gratings
Eduard R. Muslimov, Sergei N. Fabrika, Gennady G. Valyavin
In the present work we discuss a possibility to build an instrument with two operation modes - spectral and imaging ones. The key element of such instrument is a dispersive and fil…
Design and optimization of a dispersive unit based on cascaded volume phase holographic gratings
Eduard R. Muslimov, Gennady G. Valyavin, Sergei N. Fabrika +1
We describe a dispersive unit consisting of cascaded volume-phase holographic gratings for spectroscopic applications. Each of the gratings provides high diffractive efficiency in…
Advanced modelling of a moderate-resolution holographic spectrograph
Eduard Muslimov, Gennady Valyavin, Sergei Fabrika +1
In the present article we consider an accurate modeling of spectrograph with cascade of volume-phase holographic gratings. The proposed optical scheme allows to detect spectra in a…
