  • Applying differential wave-front sensing and differential power sensing for simultaneous precise and wide-range test-mass rotation measurements 
    Meshksar, Neda; Mehmet, Moritz; Isleif, Katharina-Sophie; Heinzel, Gerhard (Basel : MDPI AG, 2021)
    We propose to combine differential wave-front sensing (DWS) and differential power sensing (DPS) in a Mach-Zehnder type interferometer for measuring the rotational dynamics of a test-mass. Using the DWS method, a high ...
  • Breaking wave kinematics, local pressures, and forces on a tripod support structure 
    Hildebrandt, Arndt; Schlurmann, Torsten (Reston : American Society of Civil Engineers, 2012)
    This paper presents breaking wave loads on a tripod structure from physical model tests and numerical simulations. The large scale model tests (1:12) are described as well as the validation of the three dimensional numerical ...
  • In-Orbit Performance of the GRACE Follow-on Laser Ranging Interferometer 
    Abich, Klaus; Abramovici, Alexander; Amparan, Bengie; Baatzsch, Andreas; Bachmann Okihiro, Brian; Barr, David C.; Bize, Maxime P.; Bogan, Christina; Braxmaier, Claus; Burke, Michael J.; Clark, Ken C.; Dahl, Christian; Dahl, Katrin; Danzmann, Karsten; Davis, Mike A.; De Vine, Glenn; Dickson, Jeffrey A.; Dubovitsky, Serge; Eckardt, Andreas; Ester, Thomas; Barranco, Germán Fernández; Flatscher, Reinhold; Flechtner, Frank; Folkner, William M.; Francis, Samuel; Gilbert, Martin S.; Gilles, Frank; Gohlke, Martin; Grossard, Nicolas; Guenther, Burghardt; Hager, Philipp; Hauden, Jerome; Heine, Frank; Heinzel, Gerhard; Herding, Mark; Hinz, Martin; Howell, James; Katsumura, Mark; Kaufer, Marina; Klipstein, William; Koch, Alexander; Kruger, Micah; Larsen, Kameron; Lebeda, Anton; Lebeda, Arnold; Leikert, Thomas; Liebe, Carl Christian; Liu, Jehhal; Lobmeyer, Lynette; Mahrdt, Christoph; Mangoldt, Thomas; McKenzie, Kirk; Misfeldt, Malte; Morton, Philip R.; Müller, Vitali; Murray, Alexander T.; Nguyen, Don J.; Nicklaus, Kolja; Pierce, Robert; Ravich, Joshua A.; Reavis, Gretchen; Reiche, Jens; Sanjuan, Josep; Schütze, Daniel; Seiter, Christoph; Shaddock, Daniel; Sheard, Benjamin; Sileo, Michael; Spero, Robert; Spiers, Gary; Stede, Gunnar; Stephens, Michelle; Sutton, Andrew; Trinh, Joseph; Voss, Kai; Wang, Duo; Wang, Rabi T.; Ware, Brent; Wegener, Henry; Windisch, Steve; Woodruff, Christopher; Zender, Bernd; Zimmermann, Marcus (College Park, MD : American Physical Society, 2019)
    The Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated ...
  • Interacting quantum mixtures for precision atom interferometry 
    Corgier, Robin; Loriani, Sina; Ahlers, Holger; Posso-Trujillo, Katerine; Schubert, Christian; Rasel, Ernst M.; Charron, Eric; Gaaloul, Naceur (Bristol : IOP Publishing Ltd., 2020)
    We present a source engineering concept for a binary quantum mixture suitable as input for differential, precision atom interferometry with drift times of several seconds. To solve the non-linear dynamics of the mixture, ...
  • Measurement of the nonlinear refractive index in optical thin films 
    Steinecke, M.; Jupé, M.; Kiedrowski, K.; Ristau, D. (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Based on the z-scan method, an interferometric set-up for measuring the optical Kerr-effect was engineered and optimized. Utilizing a Mach-Zehnder configuration, the wave front deformation caused by the Kerr induced ...
  • Predictor-corrector framework for the sequential assembly of optical systems based on wavefront sensing 
    Schindlbeck, Christopher; Pape, Christian; Reithmeier, Eduard (Washington, DC : Optical Society of America, 2018)
    Alignment of optical components is crucial for the assembly of optical systems to ensure their full functionality. In this paper we present a novel predictor-corrector framework for the sequential assembly of serial optical ...
  • Tracking Length and Differential-Wavefront-Sensing Signals from Quadrant Photodiodes in Heterodyne Interferometers with Digital Phase-Locked-Loop Readout 
    Heinzel, Gerhard; Álvarez, Miguel Dovale; Pizzella, Alvise; Brause, Nils; Delgado, Juan José Esteban (College Park, MD : American Physical Society, 2020)
    We propose a method to track signals from quadrant photodiodes (QPDs) in heterodyne laser interferometers that employ digital phase-locked loops for phase readout. Instead of separately tracking the four segments from the ...
  • Wavefront predictions for the automated assembly of optical systems 
    Schindlbeck, Christopher; Pape, Christian; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 2018)
    Industrial assembly of optical systems is still a tedious and cost-intensive task that is mostly dominated by manual labor. Positional fine-adjustment of optical components is pivotal to ensure a desired performance of the ...
  • Wavefront shaping concepts for application in optical coherence tomography - a review 
    Kanngiesser, Jonas; Roth, Bernhard (Basel : MDPI AG, 2020)
    Optical coherence tomography (OCT) enables three-dimensional imaging with resolution on the micrometer scale. The technique relies on the time-of-flight gated detection of light scattered from a sample and has received ...
