Adaptive optics telemetry standard: Design and specification of a novel data exchange format (2024)
Journal Article
Gomes, T., Correia, C. M., Bardou, L., Cetre, S., Kolb, J., Kulcsár, C., …Garcia, P. (2024). Adaptive optics telemetry standard: Design and specification of a novel data exchange format. Astronomy & Astrophysics, 686, Article A7. https://doi.org/10.1051/0004-6361/202348486

Context. The amount of adaptive optics (AO) telemetry generated by visible/near-infrared ground-based observatories is ever greater, leading to a growing need for a standardised data exchange format to support performance analysis, AO research, and d...

First stellar photons for an integrated optics discrete beam combiner at the William Herschel Telescope (2021)
Journal Article
Nayak, A. S., Labadie, L., Sharma, T. K., Piacentini, S., Corrielli, G., Osellame, R., …Roth, M. M. (2021). First stellar photons for an integrated optics discrete beam combiner at the William Herschel Telescope. Applied Optics, 60(19), D129-D142. https://doi.org/10.1364/ao.423881

We present the first on-sky results of a four-telescope integrated optics discrete beam combiner (DBC) tested at the 4.2 m William Herschel Telescope. The device consists of a four-input pupil remapper followed by a DBC and a 23-output reformatter. T...

ELT-scale elongated LGS wavefront sensing: on-sky results (2021)
Journal Article
Bardou, L., Gendron, E., Rousset, G., Gratadour, D., Basden, A., Bonaccini Calia, D., …Vidal, F. (2021). ELT-scale elongated LGS wavefront sensing: on-sky results. Astronomy & Astrophysics, 649, Article A158. https://doi.org/10.1051/0004-6361/202038330

Context. Laser guide stars (LGS) allow adaptive optics (AO) systems to reach greater sky coverage, especially for AO systems correcting the atmospheric turbulence on large fields of view. However LGS suffer from limitations, among which is their appa... Read More about ELT-scale elongated LGS wavefront sensing: on-sky results.
