Abstract

Wavefront sensors encode phase information of an incoming wavefront into an intensity pattern that can be measured on a camera. Several kinds of wavefront sensors (WFS) are used in astronomical adaptive optics. Amongst them, Fourier-based wavefront sensors perform a filtering operation on the wavefront in the focal plane. The most well known example of a WFS of this kind is the Zernike wavefront sensor, and the pyramid wavefront sensor (PWFS) also belongs to this class. Based on this same principle, new WFSs can be proposed such as the n-faced pyramid (which ultimately becomes an axicone) or the flattened pyramid, depending on whether the image formation is incoherent or coherent. In order to test such novel concepts, the LOOPS adaptive optics testbed hosted at the Laboratoire d'Astrophysique de Marseille has been upgraded by adding a Spatial Light Modulator (SLM). This device, placed in a focal plane produces high-definition phase masks that mimic otherwise bulk optic devices. In this paper, we first present the optical design and upgrades made to the experimental setup of the LOOPS bench. Then, we focus on the generation of the phase masks with the SLM and the implications of having such a device in a focal plane. Finally, we present the first closed-loop results in either static or dynamic mode with different WFS applied on the SLM., Comment: 14 pages, 9 figures, submitted to JATIS

Abstract

Investigations into the Pyramid wavefront sensor (P-WFS) have experimentally demonstrated the ability toachieve a better performance than with a standard Shack-Hartmann sensor (SH-WFS). Implementation on theLarge Binocular Telescope (LBT) provided the rst operational demonstration on a facility-class instrument ofa P-WFS on sky. The desire to implement a Pyramid on an Extremely Large Telescope (ELT) requires furthercharacterisation in order to optimise the performance and match our knowledge and understanding of otherwave-front sensors (WFSs).Within the framework of the European Extremely Large Telescope (E-ELT), the Laboratoire d'Astrophysiquede Marseille (LAM) is involved in the preparation of the Single Conjugate Adaptive Optics (SCAO) system ofHARMONI, E-ELT's 1st light integral eld spectrograph (IFU). The current baseline WFS for this adaptiveoptics system is a Pyramid WFS using a high speed and sensitive OCAM2 camera. At LAM we are currentlycarrying out laboratory demonstrations of a Pyramid-WFS, with the aim to fully characterise the behaviour ofthe Pyramid in terms of sensitivity and linear range. This will lead to a full operational procedure for the use ofthe Pyramid on-sky, assisting with current designs and future implementations. The nal goal is to provide anon sky comparison between the Pyramid and Shack-Hartmann at Observatoire de la C^ote d'Azur (OCA). Herewe present our experimental setup and preliminary results.

Abstract

LAM is developing several R&D activities for E-ELT instrumentation, in particular, different WFS concepts areinvestigated (Pyramid, ZELDA, a Zernike phase mask sensor, Phase diversity or still NL Curvature) and an ESO-EELTM1 mirror segment (1.5 m) has been demonstrated. Segmented mirrors are not only the solution for the problem of ELTsmonolithic size but also for other questions related to fabrication, optics replacement and transport. And, they are widelyused today for other applications: fiber coupling, LGS beam shaping, etc. Their only problem is how to assure thecophasing of segments to take advantage of the full optimum size. In the present work, we study the sensitivity todifferent WFS (Sack-Hartmann, Pyramid and ZELDA) to pupil phase discontinuity using a PTT mirror from Iris AO.Various test such as segment phasing, stability, saturation, flat, or still the addressing mode are then performed andcompared.

Abstract

International audience; HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 450nm to 2450nm with resolving powers from 3500 to 18000 and spatial sampling from 60mas to 4mas. It can operate in two Adaptive Optics modes - SCAO (including a High Contrast capability) and LTAO - or with NOAO. The project is preparing for final design review (FDR). The Natural Guide Star Sensors (NGSS) system of HARMONI provides wavefront and image stabilisation sensing for each of the four observing modes of the instrument, LTAO, SCAO, HCAO, and NOAO. It consists of five subsystems, three of which provide wavefront sensing (LOWFS, SCAOS and HCM), the remaining two (ESE and ISB) providing thermal and mechanical functions. To limit thermal background and to ensure the required stability, the sensors operate in a cold, thermally stabilized, dry gas environment. This paper presents the overall design of the system with emphasis on system analysis, assembly and test, and maintenance.

Abstract

International audience; The adaptive optics systems of future Extremely Large Telescopes (ELTs) will be assisted with laser guide stars (LGS) which will be created in the sodium layer at a height of ≈90 km above the telescopes. In a Shack–Hartmann wavefront sensor, the long elongation of LGS spots on the sub-pupils far apart from the laser beam axis constraints the design of the wavefront sensor (WFS) which must be able to fully sample the elongated spots without undersampling the non-elongated spots. To fulfill these requirements, a newly released large complementary metal oxide semiconductor sensor with 1100 × 1600 pixels and 9 μm pixel pitch could be employed. Here, we report on the characterization of such a sensor in terms of noise and linearity, and we evaluate its performance for wavefront sensing based on the spot centroid variations. We then illustrate how this new detector can be integrated into a full LGS WFS for both the European Southern Observatory’s ELT and the Thirty Meter Telescope.; Les systèmes d'optique adaptative des futurs Extremely Large Telescopes (ELT) seront assistés par des étoiles guides laser (LGS) qui seront créées dans la couche de sodium à une hauteur de ≈90 km au-dessus des télescopes. Dans un capteur de front d'onde de Shack-Hartmann, la longue élongation des taches LGS sur les sous-pupilles éloignées de l'axe du faisceau laser contraint la conception du capteur de front d'onde (WFS) qui doit être capable d'échantillonner entièrement les taches allongées sans sous-échantillonner les taches non allongées. Pour répondre à ces exigences, un grand capteur à semi-conducteurs d'oxyde de métal complémentaire récemment commercialisé avec 1100 × 1600 pixels et un pas de pixel de 9 μm pourrait être employé. Nous présentons ici la caractérisation d'un tel capteur en termes de bruit et de linéarité, et nous évaluons ses performances pour la détection du front d'onde en fonction des variations du centroïde du spot. Nous illustrons ensuite comment ce nouveau détecteur peut être intégré dans un WFS LGS complet pour l'ELT de l'Observatoire européen austral et le télescope de trente mètres.

Abstract

International audience; Wavefront sensors encode phase information of an incoming wavefront into an intensity pattern that can be measured on a camera. Several kinds of wavefront sensors (WFS) are used in astronomical adaptive optics. Amongst them, Fourier-based wavefront sensors perform a filtering operation on the wavefront in the focal plane. The most well known example of a WFS of this kind is the Zernike wavefront sensor, and the pyramid wavefront sensor (PWFS) also belongs to this class. Based on this same principle, new WFSs can be proposed such as the n-faced pyramid (which ultimately becomes an axicone) or the flattened pyramid, depending on whether the image formation is incoherent or coherent. In order to test such novel concepts, the LOOPS adaptive optics testbed hosted at the Laboratoire d'Astrophysique de Marseille has been upgraded by adding a Spatial Light Modulator (SLM). This device, placed in a focal plane produces high-definition phase masks that mimic otherwise bulk optic devices. In this paper, we first present the optical design and upgrades made to the experimental setup of the LOOPS bench. Then, we focus on the generation of the phase masks with the SLM and the implications of having such a device in a focal plane. Finally, we present the first closed-loop results in either static or dynamic mode with different WFS applied on the SLM.

Abstract

When combined with the huge collecting area of the ELT, MOSAIC will be the most effective and flexible Multi-Object Spectrograph (MOS) facility in the world, having both a high multiplex and a multi-Integral Field Unit (Multi-IFU) capability. It will be the fastest way to spectroscopically follow-up the faintest sources, probing the reionisation epoch, as well as evaluating the evolution of the dwarf mass function over most of the age of the Universe. MOSAIC will be world-leading in generating an inventory of both the dark matter (from realistic rotation curves with MOAO fed NIR IFUs) and the cool to warm-hot gas phases in z=3.5 galactic haloes (with visible wavelenth IFUs). Galactic archaeology and the first massive black holes are additional targets for which MOSAIC will also be revolutionary. MOAO and accurate sky subtraction with fibres have now been demonstrated on sky, removing all low Technical Readiness Level (TRL) items from the instrument. A prompt implementation of MOSAIC is feasible, and indeed could increase the robustness and reduce risk on the ELT, since it does not require diffraction limited adaptive optics performance. Science programmes and survey strategies are currently being investigated by the Consortium, which is also hoping to welcome a few new partners in the next two years.
