Abstract
The use of metrology devices such as portable measuring arms, CMM and 3D scanners is increasingly widespread in the field of astronomical instrumentation. These tools are used to align the optical and mechanical parts of these instruments, thus making it possible to respect very strict positioning tolerances, often below 100 microns for a complex optomechanical assembly.
In this context, the presentation will focus on the exoplanet detection astronomical instrument NIRPS (Near Infra-Red Planet Searcher), more precisely on the assembly, integration, test and validation (AITV) phase of the spectrograph of the instrument. I will also discuss the AITV mission at the European Southern Observatory – La Silla in the Chilean desert in 2022. This presentation is a great opportunity for those who are interested in astronomy, who want to learn more about the field of astronomical instrumentation and potential future collaborations, or who simply wish to see the magnificent landscapes of Chile.
Biography
Anne-Sophie Poulin-Girard received her Ph.D. from Université Laval in 2016, under the supervision of Profs. Simon Thibault and Denis Laurendeau. Her thesis focused on the use of panoramic lenses in 3D reconstruction, at the boundary between optical engineering and computer vision. Following her Ph.D., she became the scientific coordinator of the Canada Excellence Research Chair in Neurophotonics. In 2017, she returned to Prof. Thibault’s team as a research associate. She is also scientific and technical coordinator of the NSERC Industrial chair in optical design. She currently participates in several research and development projects in collaboration with industry, and is involved in the assembly, integration and testing phase for the spectrograph of NIRPS, an instrument dedicated to the detection of exoplanets. Passionate about education, she was the chair of the SPIE Education committee and has hosted the international conference SPIE/OSA/IEEE/ICO Education and Training in optics and photonics in 2019 and is the co-chair of Optics Education and Outreach conference at SPIE O+P since 2020. Since 2021, she is also a member of the Natural Sciences and Engineering Research Council of Canada (NSERC).
The presentation will be given in French and the slides will be in English.
