Hence, the perception chain for autonomous driving is safeguarded against perturbations by imposing exaggerated optical quality requirements. Due to the non-linear coupling of optical elements, system requirements of camera-based Advanced Driver Assistance Systems (ADAS) can not be easily decomposed into individual part tolerances of the objective lens and the windscreen. This holds true for intensity-based part measurements, e.g. slanted edge measurements according to ISO12233, which can fundamentally not capture interference effects of the complex light field. Instead wavefront-based part measurements are required. Unfortunately, state-of-the-art wavefront measurement techniques are limited by the spanned sensitive area of the Shack-Hartmann lenslet array or the aperture stop of a corresponding interferometrical setup, respectively. Further, both measurements are limited by using collimated light only, whereas the target application has a large (angular) field of view, requiring many different measurements. We address those bottlenecks by proposing a novel wavefront aberration measurement procedure based on the Background Oriented Schlieren (BOS) method utilizing image auto-correlation. We analytically derive the governing equations for determining the Zernike coefficients of a wavefront aberration map in the knowledge of the local refractive power map obtained by a high-resolution BOS measurement. Furthermore, we experimentally demonstrate the feasibility of the measurement technique. Applying this novel method yields the promise of affordable wavefront aberration measurements only requiring a high-resolution camera and a sophisticated alignment strategy.}, language = {en} } @inproceedings{RituperGottkehaskamp2022, author = {Rituper, Jannik and Gottkehaskamp, Raimund}, title = {Consideration of the Saturation in a Transient Model of Line-Start Synchronous Reluctance Machines}, series = {2022 International Conference on Electrical Machines (ICEM)}, booktitle = {2022 International Conference on Electrical Machines (ICEM)}, publisher = {IEEE}, doi = {10.1109/ICEM51905.2022.9910731}, pages = {62 -- 68}, year = {2022}, subject = {Reluktanzmaschine}, language = {en} } @book{RiessWallraff2024, author = {Rieß, Bernhard and Wallraff, Christoph}, title = {{\"U}bungsbuch Signale und Systeme}, edition = {4.

Circulating fields with a switchable sense of rotation (clockwise, CW or counter clockwise, CCW) have been generated on a micrometer length scale at frequencies up to 1 GHz by two orthogonal electric RF currents with 90° phase shift flowing through crossed but not isolated striplines. Decoupling of these currents is realized by balanced symmetric RF sources. The amplitudes of the rotating magnetic fields and their spatial distributions are calculated and the stripline geometry is discussed.

In the automotive industry it is used to qualify camera systems for ADAS/AD. Each modern ADAS/AD system includes evaluation algorithms for environment perception and decision making that are based on AI/ML methods and neural networks. The performance of these AI algorithms is measured by established metrics like Average Precision (AP) or precision-recall-curves. In this article we research the robustness of the link between the optical quality metric and the AI performance metric. A series of numerical experiments were performed with object detection and instance segmentation algorithms (cars, pedestrians) evaluated on image databases with varying optical quality. We demonstrate with these that for strong optical aberrations a distinct performance loss is apparent, but that for subtle optical quality differences - as might arise during production tolerances - this link does not exhibit a satisfactory correlation. This calls into question how reliable the current industry practice is where a produced camera is tested end-of-line (EOL) with the MTF, and fixed MTF thresholds are used to qualify the performance of the camera-under-test.}, language = {en} } @inproceedings{TischbeinFatemiWirtzetal.2023, author = {Tischbein, Franziska and Fatemi, Armin and Wirtz, Frank and Schmoger, Christin and Dorendorf, Stefan and Schurtz, Annika and Echternacht, David and Ulbig, Andreas}, title = {Development of Strategies for the Smartification of Low-Voltage Grids}, series = {ETG-Fb. 170: ETG Kongress 2023 : Die Energiewende beschleunigen, 25. - 26.05.2023 in Kasse}, volume = {ETG-Fachberichte 170}, booktitle = {ETG-Fb. 170: ETG Kongress 2023 : Die Energiewende beschleunigen, 25. - 26.05.2023 in Kasse}, publisher = {VDE}, address = {Berlin}, isbn = {978-3-8007-6108-1}, pages = {438 -- 444}, year = {2023}, language = {en} } @inproceedings{LangmannStiller2017, author = {Langmann, Reinhard and Stiller, Michael}, title = {Cloud-based industrial control services - The next generation PLC?}, series = {Online Engineering \& Internet of Things: Proceedings of the 14th International Conference on Remote Engineering and Virtual Instrumentation REV 2017, held 15-17 March 2017, Columbia University, New York, USA}, volume = {Lecture Notes in Networks and Systems : 22}, booktitle = {Online Engineering \& Internet of Things: Proceedings of the 14th International Conference on Remote Engineering and Virtual Instrumentation REV 2017, held 15-17 March 2017, Columbia University, New York, USA}, editor = {Auer, Michael E. and Zutin, Danilo G.}, publisher = {Springer Nature}, address = {Cham}, isbn = {978-3-319-64351-9}, issn = {2190-4111}, doi = {10.1007/978-3-319-64352-6_1}, pages = {3 -- 18}, year = {2017}, language = {en} } @article{SchwungYuwonoSchwungetal.2022, author = {Schwung, Dorothea and Yuwono, Steve and Schwung, Andreas and Ding, Steven X.}, title = {PLC-Informed Distributed Game Theoretic Learning of Energy-Optimal Production Policies}, series = {IEEE Transactions on Cybernetics}, journal = {IEEE Transactions on Cybernetics}, publisher = {IEEE}, issn = {2168-2267}, doi = {10.1109/TCYB.2022.3179950}, pages = {1 -- 14}, year = {2022}, language = {en} } @article{QuevalSoteloKharmizetal.2016, author = {Queval, Loic and Sotelo, Guilherme G. and Kharmiz, Yassin and Dias, Daniel H.

However, the great successes of these evaluation methods in environment perception and also driving planning are accompanied by equally great challenges in the validation and verification of these systems. One of the essential aspects for this is the required guaranteed safety of the functions under mass production conditions of the vehicles. This article explains this point of view using a detailed example from the field of camera-based driver assistance systems: the determination of inspection limits at the end of the production line. The camera is one of the most important sensor modalities for vehicle environment sensing and as such, the quality of the camera systems plays a key role in the safety argumentation of the overall system. Several illustrative application examples (role of simulations, calibration, influence of the windshield) will be presented.

Although optical designs often have complex interactions with downstream image processing or analysis tasks, today's compound optics are designed in isolation from these interactions. Existing optical design tools aim to minimize optical aberrations, such as deviations from Gauss' linear model of optics, instead of application-specific losses, precluding joint optimization with hardware image signal processing (ISP) and highly parameterized neural network processing. In this article, we propose an optimization method for compound optics that lifts these limitations. We optimize entire lens systems jointly with hardware and software image processing pipelines, downstream neural network processing, and application-specific end-to-end losses. To this end, we propose a learned, differentiable forward model for compound optics and an alternating proximal optimization method that handles function compositions with highly varying parameter dimensions for optics, hardware ISP, and neural nets. Our method integrates seamlessly atop existing optical design tools, such as Zemax. We can thus assess our method across many camera system designs and end-to-end applications. We validate our approach in an automotive camera optics setting--together with hardware ISP post processing and detection--outperforming classical optics designs for automotive object detection and traffic light state detection. For human viewing tasks, we optimize optics and processing pipelines for dynamic outdoor scenarios and dynamic low-light imaging. We outperform existing compartmentalized design or fine-tuning methods qualitatively and quantitatively, across all domain-specific applications tested.}, language = {en} } @inproceedings{MuellerLehmannBraun2020, author = {Mueller, Patrick and Lehmann, Matthias and Braun, Alexander}, title = {Simulating tests to test simulation}, series = {IS\&T International Symposium on Electronic Imaging 2020: Autonomous Vehicles and Machines, 26 January 2020 — 30 January 2020, Burlingame, CA, USA}, volume = {2020}, booktitle = {IS\&T International Symposium on Electronic Imaging 2020: Autonomous Vehicles and Machines, 26 January 2020 — 30 January 2020, Burlingame, CA, USA}, number = {16}, publisher = {Society for Imaging Science and Technology}, doi = {10.2352/ISSN.2470-1173.2020.16.AVM-149}, year = {2020}, language = {en} } @article{KrebsMuellerBraun2021, author = {Krebs, Christian and M{\"u}ller, Patrick and Braun, Alexander}, title = {Impact of Windshield Optical Aberrations on Visual Range Camera Based Classification Tasks Performed by CNNs}, series = {London Imaging Meeting}, volume = {2021}, journal = {London Imaging Meeting}, number = {1}, publisher = {Ingenta connect}, isbn = {0-89208-346-6}, issn = {2694-118X}, doi = {10.2352/issn.2694-118X.2021.LIM-83}, pages = {83 -- 87}, year = {2021}, language = {de} } @inproceedings{JohanningBraunElmanetal.2007, author = {Johanning, M. and Braun, Alexander and Elman, V. and Wunderlich, Chr. and Neuhauser, W.}, title = {Individual Addressing with Trapped Yb+ Ions}, series = {2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 17.06.2007 - 22.06.2007, Munich, Germany}, booktitle = {2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 17.06.2007 - 22.06.2007, Munich, Germany}, publisher = {IEEE}, address = {M{\"u}nchen}, isbn = {978-1-4244-0930-3}, doi = {10.1109/CLEOE-IQEC.2007.4386787}, pages = {1}, year = {2007}, language = {en} } @article{JohanningBraunTimoneyetal.2009, author = {Johanning, M. and Braun, Alexander and Timoney, N. and Elman, V. and Neuhauser, W. and Wunderlich, Chr}, title = {Individual addressing of trapped ions and coupling of motional and spin states using RF radiation}, series = {Physical review letters}, volume = {102}, journal = {Physical review letters}, number = {7}, publisher = {American Physical Society}, issn = {1079-7114}, doi = {10.1103/PhysRevLett.102.073004}, year = {2009}, abstract = {Individual electrodynamically trapped and laser cooled ions are addressed in frequency space using radio-frequency radiation in the presence of a static magnetic field gradient.

Single droplet investigations serve as, among other purposes, a preliminary study for spray and combustion researchers. The described setup provides a valuable tool for the evaluation of microdroplet investigations with laser-spectroscopic techniques that rely on laser-induced fluorescence (LIF) or similar spectroscopical phenomena. The emphasis is that both spatial and spectral information are obtained from single-shot images of a falling droplet. Furthermore, combining spatial imaging and a spatially resolving optical multichannel analyzer makes a pointwise rastering of the droplets spectrum possible. This allows for the (almost) unambiguous determination of sources of influence on the spectrum of these droplets-such as geometrical distortion and lasing, nondissolved tracer lumps, and similar phenomena. Although the focus is on the experimental technique itself, we supplement detailed studies of lasing in falling microdroplets. These results were obtained with the aim of developing a system for measuring temperature distributions in droplets and sprays. In the light of these results the practice of calibrating a droplets spectrum by use of a bulk liquid sample needs to be critically reviewed.}, language = {en} } @misc{Braun2001, author = {Braun, Alexander}, title = {Laserspektroskopische Messverfahren zur Temperaturbestimmung in Sprays}, publisher = {Georg-August-Universit{\"a}t G{\"o}ttingen}, address = {G{\"o}ttingen}, organization = {Georg-August-Universit{\"a}t G{\"o}ttingen}, year = {2001}, language = {de} } @article{BalzerBraunHannemannetal.2006, author = {Balzer, Christoph and Braun, Alexander and Hannemann, T. and Paape, Chr. and Ettler, M. and Neuhauser, W. and Wunderlich, Chr.}, title = {Electrodynamically trapped Yb+ ions for quantum information processing}, series = {Physical Review A}, volume = {73}, journal = {Physical Review A}, number = {4}, publisher = {American Physical Society}, issn = {2469-9934}, doi = {10.1103/PhysRevA.73.041407}, year = {2006}, language = {en} } @article{HeizmannBraunGlitzneretal.2022, author = {Heizmann, Michael and Braun, Alexander and Glitzner, Markus and G{\"u}nther, Matthias and Hasna, G{\"u}nther and Kl{\"u}ver, Christina and Krooß, Jakob and Marquardt, Erik and Overdick, Michael and Ulrich, Markus}, title = {Implementing machine learning: chances and challenges}, series = {at - Automatisierungstechnik}, volume = {70}, journal = {at - Automatisierungstechnik}, number = {1}, publisher = {De Gruyter}, address = {Berlin}, issn = {2196-677X}, doi = {10.1515/auto-2021-0149}, pages = {90 -- 101}, year = {2022}, language = {en} } @incollection{ChristmannBusboomFeigeetal.2020, author = {Christmann, Simon and Busboom, Imke and Feige, Volker K.S. and Haehnel, Hartmut}, title = {Towards Automated Quality Inspection Using a Semi-Mobile Robotized Terahertz System}, series = {2020 Third International Workshop on Mobile Terahertz Systems (IWMTS)}, booktitle = {2020 Third International Workshop on Mobile Terahertz Systems (IWMTS)}, publisher = {IEEE}, address = {Essen}, isbn = {978-1-7281-5598-2}, doi = {10.1109/IWMTS49292.2020.9166259}, pages = {1 -- 5}, year = {2020}, language = {en} } @article{SchullerVlasenkoEybenetal.2010, author = {Schuller, Bjorn and Vlasenko, Bogdan and Eyben, Florian and Wollmer, Martin and Stuhlsatz, Andr{\´e} and Wendemuth, Andreas and Rigoll, Gerhard}, title = {Cross-Corpus Acoustic Emotion Recognition: Variances and Strategies}, series = {IEEE Transactions on Affective Computing}, volume = {1}, journal = {IEEE Transactions on Affective Computing}, number = {2}, publisher = {IEEE}, doi = {10.1109/t-affc.2010.8}, pages = {119 -- 131}, year = {2010}, language = {en} } @article{LyalinaLangmannKrisilov2011, author = {Lyalina, Yuliya and Langmann, Reinhard and Krisilov, V.}, title = {The Interaction Model in iLearning Environments and its Use in the Smart Lab Concept}, series = {International Journal of Online Engineering}, volume = {7}, journal = {International Journal of Online Engineering}, number = {4}, publisher = {iJOE}, doi = {10.3991/ijoe.v7i4.1793}, year = {2011}, language = {en} } @article{QuevalGottkehaskamp2015, author = {Queval, Loic and Gottkehaskamp, Raimund}, title = {Analytical Field Calculation of Modulated Double Helical Coils}, series = {IEEE Transactions on Applied Superconductivity}, volume = {25}, journal = {IEEE Transactions on Applied Superconductivity}, number = {6}, publisher = {IEEE}, doi = {10.1109/tasc.2015.2477377}, pages = {1 -- 7}, year = {2015}, language = {en} } @article{Franz1996, author = {Franz, J{\"u}rgen}, title = {Benefits of Communication Methods in Environmental Protection}, series = {IETE Technical Review}, volume = {13}, journal = {IETE Technical Review}, number = {3}, publisher = {Taylor \& Francis}, doi = {10.1080/02564602.1996.11416600}, pages = {153 -- 162}, year = {1996}, language = {en} } @article{JainFranz2004, author = {Jain, V.
