Design and modelling of spectrographs with holographic gratings on freeform surfaces
Eduard R. Muslimov, Marc Ferrari, Emmanuel Hugot +6
In the present paper we demonstrate the approach of using a holographic grating on a freeform surface for advanced spectrographs design. We discuss the surface and groove pattern d…
James Webb Space Telescope Optical Simulation Testbed V: Wide-field phase retrieval assessment
Iva Laginja, Greg Brady, Remi Soummer +14
The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a hardware simulator for wavefront sensing and control designed to produce JWST-like images. A model of t…
Curved detectors developments and characterization: application to astronomical instruments
Simona Lombardo, Thibault Behaghel, Bertrand Chambion +8
Many astronomical optical systems have the disadvantage of generating curved focal planes requiring flattening optical elements to project the corrected image on flat detectors. Th…
Design of optical systems with toroidal curved detectors
Eduard Muslimov, Emmanuel Hugot, Marc Ferrari +4
We consider using toroidal curved detectors to improve the performance of imaging optical systems. We demonstrate that some optical systems have an anamorphic field curvature. We c…
Spectrographs with holographic gratings on freeform surfaces: design approach and application for the LUVOIR mission
Eduard Muslimov, Marc Ferrari, Emmanuel Hugot +5
In the present paper we demonstrate the approach to use a holographic grating on a freeform surface for advanced spectrographs design. On the example POLLUX spectropolarimeter medi…
Advanced optical designs of curved detectors-based two-mirrors unobscured telescopes
Eduard Muslimov, Emmanuel Hugot, Simona Lombardo +4
In the present paper we consider a family of unobscured telescope designs with curved detectors. They are based on classical two-mirror schemes -- Ritchey-Chretien, Gregorian and C…
