The far-infrared to submillimeter domain is a unique probe of the cold and obscured Universe, harboring for instance the precious signatures of key elements such as water. Space observations are mandatory given the blocking effect of our atmosphere. However the methods we have relied on so far to develop increasingly larger telescopes are now reaching a hard limit, with the JWST illustrating this in more than one way (e.g. it will be launched by one of the most powerful rocket, it requires the largest existing facility on Earth to be qualified). With the Thinned Aperture Light Collector (TALC) project, a concept of a deployable 20 m annular telescope, we propose to break out of this deadlock by developing novel technologies for space telescopes, which are disruptive in three aspects: \&\#8226; An innovative deployable mirror whose topology, based on stacking rather than folding, leads to an optimum ratio of collecting area over volume, and creates a telescope with an eight times larger collecting area and three times higher angular resolution compared to JWST from the same pre-deployed volume; \&\#8226; An ultra-light weight segmented primary mirror, based on electrodeposited Nickel, Composite and Honeycomb stacks, built with a replica process to control costs and mitigate the industrial risks; \&\#8226; An active optics control layer based on piezo-electric layers incorporated into the mirror rear shell allowing control of the shape by internal stress rather than by reaction on a structure. We present in this paper the roadmap we have built to bring these three disruptive technologies to technology readiness level 3. We will achieve this goal through design and realization of representative elements: segments of mirrors for optical quality verification, active optics implemented on representative mirror stacks to characterize the shape correction capabilities, and mechanical models for validation of the deployment concept. Accompanying these developments, a strong system activity will ensure that the ultimate goal of having an integrated system can be met, especially in terms of (a) scalability toward a larger structure, and (b) verification philosophy.}, language = {en} } @inproceedings{MuellerBackhaus2018, author = {M{\"u}ller, L. and Backhaus, C.}, title = {A methodical approach for integrating end-user usability evaluations into the procurement process of medical devices}, series = {Contribution to the Annual Meeting of German Society of Biomedical Engineering}, booktitle = {Contribution to the Annual Meeting of German Society of Biomedical Engineering}, doi = {10.1515/bmt-2018-6051}, pages = {306}, year = {2018}, language = {en} } @incollection{SchulzeDeemannHartensueretal.2010, author = {Schulze, M and Deemann, D and Hartensuer, R and Koch, R and L{\"o}hrer, L and MJ, Raschke and UM, H{\"o}lscher and Vordemvenne, T.}, title = {A New Combined Optical and Robotic Testing System to Evaluate Multisegmental Spinal Kinematics}, series = {Lim CT, Goh JCH, eds. 6th World Congress of Biomechanics (WCB 2010) August 1-6, 2010 Singapore}, booktitle = {Lim CT, Goh JCH, eds. 6th World Congress of Biomechanics (WCB 2010) August 1-6, 2010 Singapore}, publisher = {Springer}, address = {Berlin, Heidelberg}, isbn = {978-3-642-14515-5}, pages = {580 -- 583}, year = {2010}, language = {en} } @article{SchulzeDeemannHartensueretal.2010, author = {Schulze, M and Deemann, D and Hartensuer, R and L{\"o}hrer, L and MJ, Raschke and H{\"o}lscher, U and Vordemvenne, T.}, title = {A new in vitro biomechanical test system to evaluate adjacent level effects of the lumbar spine (P 62)}, series = {European Spine Journal}, volume = {19}, journal = {European Spine Journal}, pages = {233 -- 364}, year = {2010}, language = {en} } @article{StiefPeikenkamp2015, author = {Stief, T. and Peikenkamp, K.}, title = {A new insole measurement system to detect bending and torsional moments at the human foot during footwear condition: A technical report.}, series = {J Foot Ankle Res}, volume = {8}, journal = {J Foot Ankle Res}, doi = {10.1186/s13047-015-0105-6}, year = {2015}, language = {en} } @misc{Morawetz2012, author = {Morawetz, K.}, title = {A new method to calculate partition functions, 26.3.-30.3.: DPG spring meeting Berlin}, year = {2012}, language = {mul} } @inproceedings{SchuemmerMertinsAdametal.2019, author = {Sch{\"u}mmer, A. and Mertins, H.-Ch. and Adam, R. and Schneider, C.M. and B{\"u}rgler, D. and Juschkin, L. and Berges, U.}, title = {A new scanning reflection x-ray microscope for magnetic imaging in the EUV range}, series = {Verhandlungen der DPG}, volume = {2019}, booktitle = {Verhandlungen der DPG}, year = {2019}, language = {en} } @incollection{Hoelscher1987, author = {H{\"o}lscher, U.}, title = {A novel approach for an ECG electrode integrated into a transcutaneous sensor}, series = {Huch [Hrsg.]: Continous transcutaneous monitoring}, booktitle = {Huch [Hrsg.]: Continous transcutaneous monitoring}, year = {1987}, language = {en} } @article{SchuemmerMertinsSchneideretal.2019, author = {Sch{\"u}mmer, Andreas and Mertins, Hans-Christoph and Schneider, Claus Michael and Adam, Roman and Trellenkamp, Stefan and Borowski, Rene and B{\"u}rgler, Daniel and Juschkin, Larissa and Berges, Ulf}, title = {A Scanning Reflection X-ray Microscope for Magnetic Imaging in the EUV Range}, series = {Journal of Synchrotron Radiation}, volume = {2019}, journal = {Journal of Synchrotron Radiation}, number = {26}, issn = {1600-5775}, doi = {10.1107/S1600577519012219}, pages = {2040 -- 2049}, year = {2019}, abstract = {The mechanical set up of a novel scanning reflection X-ray microscope is presented.

An ablation chamber which enables ICP-MS pulse duration down to several ten milliseconds has been designed. Dependence of the ICP-MS peak amplitude, width, and shape on the gas flow parameters is studied experimentally for aerosol ablated under laminar and turbulent conditions. Experiments demonstrate that the ICP-MS peak becomes sharper and the amplitude of the signal grows as the turbulence in the ablation cell is suppressed. Furthermore, the possibility of the LA-ICP-MS analysis with a sampling rate of more than 10 Hz has been demonstrated.

The model is verified by comparing its predictions with experimental results of our prototype of a novel unimorph deformable mirror.}, language = {de} } @article{VogtWachterMehringetal.2009, author = {Vogt, J. and Wachter, A. and Mehring, U. and Radermacher, J. and Georgieff, P. and Fischer, M. and H{\"o}lscher, H. and Moede, U. and Fabinski, M.}, title = {Adaption of the NDIR-technology to 13CO2-breath tests under increased inspiratory O2 concentrations}, series = {Journal of Applied Physiology}, journal = {Journal of Applied Physiology}, number = {107}, pages = {302 -- 307}, year = {2009}, language = {en} } @inproceedings{WittrockWelp2006, author = {Wittrock, Ulrich and Welp, Petra}, title = {Adaptive laser resonator control with deformable MOEMS mirrors}, series = {MEMS/MOEMS Components and Their Applications III, Proc.

The requirements for deformable mirrors and for closed-loop control systems of these mirrors are analyzed. Several deformable mirrors have been characterized and the results are presented. Currently available membrane mirrors deform under laser load and need further development before they can be used for aberration correction of solid state lasers above some tens of Watts. Nevertheless, the results are encouraging and the requirements are within reach of currently available technology. Finally, we demonstrate an Nd.YVO4-laser with a closed-loop adaptive resonator and more than 6 W of output power.

PHELIX will offer the world-wide unique combination of a high current, high-energy heavy-ion beam with an intense laser beam. Aberrations due to the beam transport and due to the amplification process limit the focusability and the intensity at the target. We have investigated the aberrations of the different amplification stages. The pre-amplifier stage consists of three rod-amplifiers which cause mainly defocus, but also a small part of coma and astigmatism. The main amplifier consists of five disk amplifiers with a clear aperture of 315 mm. These large disk-amplifiers cause pump-shot aberrations which occur instantly. After a shot, the disk amplifiers need a cooling time of several hours to relax to their initial state. This limits the repetition rate and causes long-term aberrations. We will present first measurements of the pump-shot and long-term aberrations caused by the pre- and the main amplifier in a single-pass configuration. In this context, we will present the adaptive optics system which is implemented in the PHELIX beam line and discuss its capability to compensate for the pump-shot and long-term aberrations.}, language = {de} } @book{OPUS4-1746, title = {Adaptive optics for industry and medicine.

The femtosecond laser shock peening in the air has been studied recently, which can induce higher pressure shock wave than that of traditional nanosecond laser shock peening in a very short time. The NiTi alloy is processed by femtosecond laser shock peening, then a nanoindentation device is used to measure its surface hardness and residual stress.

The relative strength and the electron temperature dependence of the electron-phonon coupling of the metals composing the layered target are identified as major factors affecting the initial energy redistribution and the location of the region(s) undergoing transient melting and resolidification. The higher strength of the electron-phonon coupling in Cu, as compared to Au, results in a preferential sub-surface heating and melting of the Cu substrate, while the overlaying Au film largely retains its original crystalline structure. The large difference in the atomic mobility in the transiently melted and crystalline regions of the target makes it possible to connect the final distributions of the components in the resolidified targets to the history of the laser-induced melting process, thus allowing for experimental verification of the computational predictions.
