SIG Meeting Structured & Freeform Surfaces 2024 📍 Nottingham, UK Keynote Prof. Gerardo Adesso from The University of Nottingham will be presenting his keynote on Surface metrology and roughness estimation at the quantum limit. "Since the invention of optical imaging devices, such as microscopes and telescopes, there has been a quest to enhance their resolution. A fundamental limitation, known as the Rayleigh limit, is associated with diffraction: conventional optical systems cannot resolve angular separations smaller than the wavelength of the emitted light. In the last decades, a number of techniques for circumventing the diffraction limit in microscopy have been proposed, defining a field called superresolution imaging. However, these approaches are either operational in the near-field, or rely on non-linear probing, which makes them expensive, invasive, and not universally applicable. Very recently, advances in quantum metrology have revealed that these drawbacks can be bypassed and the Rayleigh limit can be beaten by applying a fundamentally different method of detection. Rather than measuring the intensity as a function of the transverse position in the collection plane (as the traditional direct imaging approach), one can measure the correlation of electromagnetic field amplitudes at different transverse positions. In practice, this involves detecting the light emitted by an object in an alternative basis of spatial modes in order to extract further information about the incoming field. In this talk I will present the fundamentals of quantum parameter estimation theory as well as their applications to superresolution imaging and surface metrology. I will present our progress in the quest to design a passive linear optical device based on spatial mode demultiplexing, capable of achieving sub-Rayleigh resolution in the reconstruction of 2D and 3D samples and in principle reaching the ultimate precision limits allowed by quantum mechanics." ~ Prof. Gerardo Adesso Biography: Gerardo Adesso is a Professor of Mathematical Physics and Director of Research in the School of Mathematical Sciences at the University of Nottingham. He received his PhD from the University of Salerno in Italy in 2007. He joined the University of Nottingham as a Lecturer in 2009 and was promoted to Associate Professor in 2014 and then to Professor in 2016. He is an expert in the fundamental characterisation and applications of genuine quantum resources to provide operational advantages in quantum technologies such as quantum communication and sensing. A former ERC Grantee, he has authored about 190 peer reviewed publications, including over 50 in Physical Review Letters, and since 2021 he is recognised as a Clarivate Highly Cited Researcher in Physics. #euspen #keynote #structuredfreeformsurfaces

SIG Meeting Structured & Freeform Surfaces 2024 📍 Nottingham, UK Keynote Prof Dragos A. from The University of Nottingham will be presenting his keynote om unified modelling approach for time-dependent processes enable accurate generation of macro, meso and micro freeforms. "We demonstrate that, despite differences in their nature, many energy beam controlled-depth machining processes (e.g. waterjet, pulsed laser, focused ion beam) can be modelled using the same mathematical framework – a partial differential evolution equation that requires only simple calibrations to capture the physics of each process. The inverse problem can be solved efficiently through numerical solution of the adjoint problem and leads to beam paths that generate prescribed three-dimensional features with minimal error. The viability of this modelling approach has been demonstrated by generating accurate freeform surfaces using three processes that operate at very different length scales and with different physical principles for material removal: waterjet, pulsed laser and focused ion beam machining. Our approach can be used to explore inverse problems for a wide range of time-dependent processes to enable a step change in generation accurate surfaces with tailored properties." ~ Prof Dragos Axinte Biography: Dragos Axinte is Professor of Manufacturing Engineering at University of Nottingham UK. Graduated at University of Galati, Romania, after working in industrial research for eight years, he held two NATO Research Fellowships in Italy and Denmark and then moved to UK to carry out research with University of Birmingham and later with University of Nottingham. He was appointed Lecturer in Manufacturing Engineering (2005) and successively promoted to Associate Professor (2007), Reader (2010) and Professor (2011). Since 2009 Dragos is Director of The Rolls-Royce UTC in Manufacturing and On-Wing Technology at University of Nottingham. Dragos is Fellow of CIRP and Editor-in-Chief of the International Journal of Machine Tools and Manufacture as well as Journal Materials Processing Technology. He has over 200 journal papers and over 30 granted international patents field with industry partners. Dragos research interest is in the main following areas: Advanced Machining and Finishing Technologies, Time-Dependent Processes such as Laser Ablation, Abrasive Waterjet Machining, Monitoring of Manufacturing Processes, Design and Construction of Miniature Machine Tolls, Design of Innovative Robotics for Aerospace Manufacture and In-Situ Repairs in Hazardous Environments and Workpiece Surface Integrity Analysis. #euspen #structuredfreeformsurfaces

SIG Meeting Structured & Freeform Surfaces 2024 📍 Nottingham, UK State-of-the-Art Dr Raoul Roth from RhySearch will be giving his talk on Free-form metal optics – manufacturing techniques and coating processes. This presentation provides an overview of the state of the art in diamond turning of freeform surfaces and the corresponding coating technologies for optical coatings. In diamond turning, it explores slow-tool and fast-tool servo techniques, illustrated by a specific example of applications. Special attention is also paid to coating technologies, with a focus on dual ion beam sputtering and atomic layer deposition. These technologies can be used to produce uniform and high-precision coatings on both flat and curved surfaces. In addition, an overview of the characterisation of optical coatings is given and, for example, the influence of different workpiece materials on the reflectivity is shown. Biography Raoul Roth completed his degree in mechanical engineering at the Swiss Federal Institute of Technology Zurich (ETHZ) in 2006. After working as a research assistant in the field of manufacturing technologies at inspire AG (technology transfer organization of ETHZ), he completed his PhD in 2014 at the Institute for Machine Tools and Manufacturing (IWF) at ETHZ under the supervision of Prof. Konrad Wegener in the field of spark erosion. After a short time at the Institute for Sustainable Development at Zurich University of Applied Science (ZHAW) he returns to the IWF as a postdoc. In his postdoctoral work, he focused on surface functionalization using spark erosion and laser technologies. Raoul Roth is now working as project leader in applied research at RhySearch since 2017. His area of responsibility includes the further development of cutting technologies, ranging from single point diamond turning to 5-axis milling in a wide variety of projects.

Congratulations to the Winners of the euspen Talent Programme 2024 We extend our heartfelt congratulations to Wayne Edgar from DTU - Technical University of Denmark, Danish Ashraf from The University of Huddersfield, UK, and Koichi Hayashi from Nagoya University, JP, for their remarkable achievement in winning the euspen Talent Programme 2024. This year's challenge, held in collaboration with Stryker, centered around the development of an MPO (Multi-fiber Push On) connector plate design. The focus was not only on the design but also on creating an efficient manufacturing process for the automated assembly and testing of the fiber optic connector performance. As part of their victory, the winners had the opportunity to visit the Stryker Technology Centre in Cork, Ireland, accompanied by our Talent committee member and 2022 winner, Adriano Nicola Pilagatti. This visit was an immersive experience into some of the world-leading medical technologies and methodologies employed by Stryker.
