CfAI news and events

CfAI participates in ICSO

Chris Graham, Perrine Lognone, Ollie Farley and Ariadna Calcines Rosario, from CfAI, participated in the International Conference on Space Optics celebrated in The Antibes in October 21^st-25^th. CfAI presented a wide range of research topics, including: folded Three Mirror Anastigmat telescope for Earth Observation CubeSat; unlocking Ground-to-Space optical links capacity with optimized AO pre-compensation using spatio-temporal measurements and priors; optimising optical ground station locations for satellite communications through atmospheric turbulence with Adaptive Optics mitigation and developing the Image Slicer technology for space applications in the EUV.

World Space Week

Researchers from Durham University’s Centre for Advanced Instrumentation Group were at the Centre for Life in Newcastle on Saturday, 5th October, for World Space Week to present an experiment on the theme “Space & Climate.” We brought gas lamps (Neon, Mercury, and Sodium), and children had the opportunity to use a spectrograph to break down the light and observe the different emission lines.

It was an excellent day for the team, with lots of questions about space and satellites—some quite unexpected—showing the interest and passion of the younger generation for Science and Technology.

Thank you, The Centre for Life, for inviting us and meet the local communities.

Advancing Metal Optics for Space Systems

The Enabling Technology Program (ETP1-040) research project, “Advancing Metal Optics for Space Systems,” funded by the UK Space Agency, is concluding at the end of this month.

The project's objective was to design, manufacture, and test a three-mirror telescope for Earth Observation, with each mirror featuring a freeform optical surface. Freeform means the mirrors lack rotational symmetry, which allowed the system to be more compact but also increased the complexity of manufacturing and testing.

The team, comprising partners from Diamond Light Source in Harwell and the Advanced Manufacturing Research Centre AMRC in Sheffield, successfully achieved most of the key objectives:
(i) successful testing of the telescope,
(ii) design and 3D printing of the telescope housing in AlSi35, an aluminium alloy known for its thermal properties,
(iii) development of a novel polishing technique using Ion Beam Figuring on Nickel, the material used for the mirrors.

The results of this project demonstrate that lightweight, space-grade housing with complex geometries can be realized through additive manufacturing, achieving significant weight reduction.

This project also acknowledges the valuable support and contributions from QED Technology and Schneider.

CfAI PhD poster celebration

On the 24th of July 2024 the PhD students did a great job producing posters and presenting them to members of the group. We thank everyone who took part and Claire for all her work organising. 

Little iLocater: paving the way for iLocater 

The Little iLocater spectrograph (Lili) saw first light at the Large Binocular Telescope in Arizona on the 16th of May. We captured spectra of bright stars, allowing spectral characterisation with the iLocater front end for the first time. We used the powerful AO of the 8.4 m telescope to separate close in binaries (50 mas) and take spectra of the individual components that cannot be resolved normally.

Testing with Lili paves the way for the iLocater spectrograph, a high resolution spectrograph which will perform detailed characterisation of exoplanets in the near-infra red.The Spectrograph

METIS Integral Field Unit for the Extremely Large Telescope

Today, we bid farewell to the METIS Integral Field Unit pupil mirror array, crafted from 28 meticulously designed slices and a composite planar fold mirror. This remarkable piece of engineering is now on its way to the UK Astronomical Technology Centre in Edinburgh, where it will undergo the final assembly process as a vital component of the METIS instrument at the focus of the Extremely Large Telescope.

METIS (Mid-infrared ELT Imager and Spectrograph) will be one of the first generation instruments for the 40m European Extremely Large Telescope (ELT). METIS is designed to be a workhorse for ground-based optical astronomy with science cases from objects in our Solar System to distant active galaxies and even probing the properties and atmospheric composition of planets orbiting distant stars.

The entire team has dedicated hours to shape this aluminium blank into a sophisticated marvel. A special shoutout to everyone involved in the metrology process, which required a highly specific setup to ensure the position measurement of each facet relative to the others.

We look forward to the significant contributions METIS will make to our understanding of the universe. Kudos to the team for their hard work and dedication in advancing astronomical technology!

The Royal Astronomical Society has awarded the RAS Group Achievement Award 2024 to the team of the instrument MIRI for the JWST.

"Following the launch of JWST on December 25th 2021, the performance of MIRI has been spectacular, producing ground-breaking scientific results encompassing our own solar system, extrasolar planets, star formation in our own and nearby galaxies, and the properties of the most distant galaxies. These scientific achievements testify to the ambition, dedication and professionalism of Professors Wright and Rieke and of the entire MIRI Team. For these reasons the JWST-MIRI Team is awarded the 2024 Group Achievement Award (A) of the RAS." 

MIRI was developed by a large international consortium, comprising many institutes in ten European countries and the United States, in partnership with ESA and NASA, including the CfAI in Durham University, and led by Professor Gillian Wright of the UK Astronomy Technology Centre and Professor George Rieke of the University of Arizona.

Communications and Observations through Atmospheric Turbulence

A multidisciplinary workshop to address the biggest challenges in free-space optical propagation from astronomy to laser communications.

More information here.

In a large variety of fields, the development of ever more demanding optical systems now requires a thorough understanding of the impact of atmospheric turbulence together with the development of dedicated mitigation strategies. Originally driven by astronomy, these issues now concern near ground imaging, satellite observation, ground-space and near ground optical free-space telecommunications and laser focusing.

The workshop aims at giving an overview of current research activities in this field. It will address turbulence impact and mitigation, especially in challenging environments such as strong turbulence, strong scintillation, high apparent wind speeds induced by target tracking, anisoplanatism effects due to the field of view or point-ahead angle.

The following topics will, therefore, be addressed during the workshop:
knowledge on turbulence conditions (modelling, characterization & prediction of both Cn² and wind profiles), including free atmosphere and local turbulence; study of system performance with and without mitigation; mitigation strategies based on innovative optical solutions such as single aperture adaptive optics, multi-aperture or aperture diversity solutions, integrated optics architectures, new wave-front sensing approaches, sensorless solutions, laser guide stars, high performance control; lastly, image/signal pre- and post-processing techniques (deconvolution, PSF prediction, digital communications techniques), novel reception schemes and advanced digital signal processing.

24 hour continuous turbulence monitoring at Paranal, Chile

Lisa Bardou and Ryan Griffiths carried out the first continuous optical turbulence monitoring at the European Southern Observatory site at Paranal, Chile.

The Shack Hartmann Image Motion Monitor (SHIMM) is the first instrument capable of measuring optical turbulence continuously day and night. This is important to support operations of optical astronomical telescopes. The night time measurements enable programme management and the daytime measurements enable continuous assimilation into turbulence forecast models.
