Co-design approach to aperture masking for imaging through atmospheric turbulence
Olivier Herscovici-Schiller, Laurent M. Mugnier, Alice Fontbonne +5
Aperture masking interferometry is a technique originally designed to alleviate the influence of atmospheric turbulence on images recorded on ground-based telescopes. In this commu…
High-contrast imager for complex aperture telescopes (HiCAT): 8. Dark zone demonstration with simultaneous closed-loop low-order wavefront sensing and control
Rémi Soummer, Emiel H. Por, Raphaël Pourcelot +27
We present recent laboratory results demonstrating high-contrast coronagraphy for the future space-based large IR/Optical/Ultraviolet telescope recommended by the Decadal Survey. T…
Near ground horizontal high resolution profiling from Shack-Hartmann slope and scintillation data
Chloé Sauvage, Clélia Robert, Laurent M. Mugnier +5
CO-SLIDAR is a very promising technique for the metrology of near ground profiles. It exploits both phase and scintillation measurements obtained with a dedicated wavefront…
Wavefront tolerances of space-based segmented telescopes at very high contrast: Experimental validation
Iva Laginja, Jean-François Sauvage, Laurent M. Mugnier +8
Context: The detection and characterization of Earth-like exoplanets (exoEarths) from space requires exquisite wavefront stability at contrast levels of . On segmented te…
Partial-Field Illumination Ophthalmoscope: improving the contrast of a camera-based retinal imager
Léa Krafft, Elena Gofas-Salas, Yann Lai-Tim +5
Effective and accurate in-vivo diagnosis of retinal pathologies requires high performance imaging devices, combining a large field of view and the ability to discriminate the balli…
Analytical tolerancing of segmented telescope co-phasing for exo-Earth high-contrast imaging
Iva Laginja, Remi Soummer, Laurent M. Mugnier +5
This paper introduces an analytical method to calculate segment-level wavefront error tolerances in order to enable the detection of faint extra-solar planets using segmented teles…
