  • Quentin, Lorenz; Beermann, Rüdiger; Pösch, Andreas; Reithmeier, Eduard; Kästner, Markus (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    We present a fringe projection system to measure glowing hot hybrid components in between production processes. For this a high power green light projector, based on TI DLP technology, is used to create the highest possible ...
  • Grabe, Tobias; Biermann, Tobias; Bayerl, Maximilian; Lachmayer, Roland (Erlangen : Deutsche Gesellschaft für angewandte Optik, 2020)
    The Additive Manufacturing of transparent materials enables cost efficient rapidprototyping of optically transparent components. The components are built layer-by-layer which can cause anisotropic optical properties. We ...
  • Stukenberg, Niklas Merten; Poehling, Hans-Michael (s.l. : BioRxiv, 2018)
    Visual orientation in the greenhouse whitefly ( Trialeurodes vaporariorum Westwood, Hemiptera: Aleyrodidae) is the result of 9wavelength-specific behaviours9. Green-yellow elicits 9settling behaviour9 while ultraviolet ...
  • Chwalla, M.; Danzmann, Karsten; Fernández Barranco, G.; Fitzsimons, E.; Gerberding, Oliver; Heinzel, Gerhard; Killow, Christian J.; Lieser, M.; Perreur-Lloyd, M.; Robertson, D.I.; Schuster, Sönke; Schwarze, Thomas S.; Tröbs, M.; Ward, H.; Zwetz, M. (Bristol : IOP Publishing, 2016)
    The laser interferometer space antenna (LISA) is a future space-based interferometric gravitational-wave detector consisting of three spacecraft in a triangular configuration. The interferometric measurements of path length ...
  • Hachicha, B.; Overmeyer, Ludger (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Polymer optical waveguides, especially single-mode waveguides are increasingly used for short distance communication, as well as for sensing applications. The realization of a working communication route requires different ...
  • Reitberger, T.; Stoll, T.; Hoffmann, G.-A.; Lorenz, L.; Neermann, S.; Overmeyer, L.; Bock, K.-H.; Wolter, K.-J.; Franke, J. (Cambridge : Cambridge University Press, 2018)
    One of today's megatrends in the industrial environment is additive manufacturing. Faster prototyping, customized products like hearing devices, integrated functions like heatsinks and many other opportunities are offered ...
  • Aghayari, S.; Saadatseresht, Mohammad; Omidalizarandi, Mohammad; Neumann, Ingo (Göttingen : Copernicus GmbH, 2017)
    A novel calibration process of RICOH-THETA, full-view fisheye camera, is proposed which has numerous applications as a low cost sensor in different disciplines such as photogrammetry, robotic and machine vision and so on. ...
  • Beermann, Rüdiger; Quentin, Lorenz; Pösch, Andreas; Reithmeier, Eduard; Kästner, Markus (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    In the manufacturing process of Tailored Forming components, the inline inspection of the joining zone directly after each single process step can yield advantages - such as early error detection and real-time process ...
  • Melchert, O.; Roth, B.; Morgner, Uwe; Demircan, A. (Amsterdam : Elsevier B.V., 2019)
    A Python package for the calculation of spectrograms with optimized time and frequency resolution for application in the analysis of numerical simulations on ultrashort pulse propagation is presented. Gabor’s uncertainty ...
  • Schlobohm, Jochen; Pösch, Andreas; Reithmeier, Eduard (Basel : MDPI AG, 2016)
    Geometry measurements are very important to monitor a machine part’s health and performance. Optical measurement system have several advantages for the acquisition of a parts geometry: measurement speed, precision, point ...
  • Pospiech, Matthias; Emons, Moritz; Kuetemeyer, Kai; Heisterkamp, Alexander; Morgner, Uwe (Washington, DC : Optical Society of America, 2011)
    We report on femtosecond nanosurgery of fluorescently labeled structures in cells with a spatially superresolved laser beam. The focal spot width is reduced using phase filtering applied with a programmable phase modulator. ...
  • Grabe, Tobias (Hannover : Institut für Produktentwicklung und Gerätebau, Gottfried Wilhelm Leibniz Universität, 2014-09-25)
    Helle, weiße LEDs kommen zunehmend in Neuentwicklungen von Fahrzeugscheinwerfern als Ersatz für klassische Xenon- und Halogen-Lichtquellen zum Einsatz. Einen nächsten Schritt in dieser Entwicklung stellen Lichtquellen auf ...
  • Buchkremer, F.B.J.; Dumke, R.; Levsen, H.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 2000)
    A new echo technique to access the coherent and dissipative dynamics of atomic wave packet oscillations in trapping potentials was experimentally and systematically validated. By using this technique, the coherence time ...
