Groupe R&D Optique & Instrumentation

Recherche et Développement en Optique, Instrumentation, Télescopes et Détecteurs

Le pôle de R&D en optique et instrumentation, fondé en 1970 par André Baranne, travaille à l’amélioration des performances de l’instrumentation astronomique par le développement de nouveaux concepts et une recherche de pointe en optique. Tout en participant aux programmes majeurs d’instrumentation astronomique, l’équipe mène des activités de R&D amont dans de nombreux domaines. Son activité d’innovation instrumentale permet d’établir des liens transverses entre les pôles de recherche les plateformes technologiques et les services techniques du LAM.

Dernières nouvelles

July 2020
On-going... Stay tuned !

June 2020
This month, the HiRISE visitor instrument proposal has been officially submitted to ESO by the team. The proposal is the results of a 2-year study done in collaboration with partners from France, Germany, Chile and the United-Kingdom. The proposal will now be evaluated by ESO and hopefully validated by the STC. In the meantime the development will continue with the goal to reach a final design by the end of the year. Congrats to the HiRISE team !
This month too, the Società Astronomica Italiana awarded the Giuseppe Lorenzoni prize to Simona LOMBARDO for her paper "SCALA : In situ calibration for integral field spectrographs", thus recognising her major PhD work. Congrats Simona !
Also this month, The LUVOIR team for the 2020 Decadal has been recently awarded with the NASA Group Achievement Award for the LUVOIR Science and Technical Definition Team (STDT) as well as several Robert H. Goddard awards for the LUVOIR STDT, the engineering team and key people. Congrats to the LUVOIR team, which included Marc FERRARI as international member and had a significant LAM contribution for the POLLUX instrument study !
Finally, two new papers were published in the team this June 2020 :
Fetick et al., accepted in MNRAS :Blind deconvolution in astronomy with adaptive optics : the parametric marginal approach
Lombardo et al., white paper on ArXiv : CASTLE : performances and science cases.

May 2020
The prestigious Great Science Prize of the Charles Defforey Foundation as been awarded this month to the six lead actors in the design and realization of the SPHERE instrument, among which our very own GRD members Jean-Luc BEUZIT and Thierry FUSCO. A well-deserved award ! Congratulations to the team !

Following his postdoc position at ONERA/LAM, Olivier BELTRAMO-MARTIN is starting a new postdoc position at LAM this month. Olivier will now work for the ANR APPLY on the development of Artificial Intelligence techniques for PSF reconstruction and AO-assisted data post-processing. Congrats !
Also this month, several GRD members took part to the first (virtual) face-to-face meeting of the ELT Working Groups organized by ESO to prepare for observations with the ELT.
Also, this month the MAVIS Phase A document, in which GRD members have been significantly involved, was submitted to ESO, for an official review May 26-27.
Finally, a new publication from the team was accepted for publication in A&A. Congrats Vincent CHAMBOULEYRON !
Chambouleyron et al., accepted in A&A : Pyramid wavefront sensor Optical Gains compensation using a convolutional model

April 2020
New article from PhD student Anne-Laure Cheffot et al. published in Optics Express about Measuring the cophasing state of a segmented mirror with a wavelength sweep and a Zernike phase contrast sensor. Congrats !

March 2020
During the confinement set against the COVID19 pandemic, the GRD group is still fully operational. Most of our research can be done by teleworking and remote control of our testbeds.
Unfortunately, the starting date of two new members has to be postponed, although both have been integrated to the team through our remote communication channels.
Iva LAGINJA, 2nd year PhD student in partnership between STScI (Baltimore, R. Soummer) and ONERA (JF Sauvage, T. Fusco). Iva works on cophasing segmented telescopes for high-contrast imaging applications. After 1.5yr at Baltimore, Iva is to finish her PhD program here at LAM.
Felipe BUSTOS PEDREROS, Marie Curie postdoctoral Fellow. Felipe works on wavefront sensing techniques using laser guide stars.
Welcome to the team !
Finally, this month we had three new publications in the team :
Lemared, Ferrari, et al., accepted in Optics Express : Stress mirror polishing for future large lightweight mirrors : design using shape optimization.
Correia, Fauvarque, et al., accepted in MNRAS : Performance limits of adaptive-optics/high contrast imagers with pyramid wave-front sensors
Fusco et al., accepted in A&A : Reconstruction of the ground-layer adaptive-optics point spread function for MUSE Wide Field Mode observations
