  • Kruse, I.; Lange, K.; Peise, J.; Lücke, Bernd; Pezzè, L.; Arlt, Jan J.; Ertmer, Wolfgang; Lisdat, C.; Santos, Luis; Smerzi, A.; Klempt, Carsten (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferometer, an ensemble of atoms is prepared in ...
  • Wübbold, Frauke; Hentschel, Matthias; Vousdoukas, Michalis I.; Wagner, Bernardo (Reston : American Society of Civil Engineers, 2012)
    Beach topographic and hydrodynamic measurements are essential for coastal geology and engineering studies as well as sustainable coastal management. Standard approaches involve either time-consuming manual data acquisition ...
  • Rolfes, I.; Will, B.; Schiek, B. (Göttingen : Copernicus GmbH, 2008)
    With the availability of multi-port vector network analyzers, the need for automated, calibrated measurement facilities increases. In this contribution, a calibrationmeasurement unit is presented which realizes a repeatable ...
  • Wittchen, A.; et al.; LPF Collaboration (Bristol : Institute of Physics Publishing, 2017)
    LISA Pathfinder is a technology demonstration mission for the space-based gravitational wave observatory, LISA. It demonstrated that the performance requirements for the interferometric measurement of two test masses in ...
  • Li, Yinan; Bossmeyer, Hagen; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Common 2D laser line triangulation sensors allow a 2D profile measurement in a single line. To scan samples with great curved surfaces like edges, a single laser line triangulation sensor is insufficient. To measure the ...
  • Jacobsen, Karsten (Hannover : International Society for Photogrammetry and Remote Sensing, 2010)
    Digital aerial cameras have replaced analogue aerial cameras in several countries. The development for operational aerial photogrammetry started with the line scan camera ADS40, followed by Z/I Imaging DMC and Vexcel Imaging ...
  • Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Inspection of machine elements is an important task in production processes in order to ensure the quality of produced parts and to gather feedback for the continuous improvement process. A new measuring system is presented, ...
  • Audley, Heather E.; LISA Pathfinder Collaboration (Bristol : Institute of Physics Publishing, 2017)
    The LISA Pathfinder (LPF) mission has demonstrated excellent performance. In addition to having surpassed the main mission goals, data has been collected from the various subsystems throughout the duration of the mission. ...
  • Freier, C.; Hauth ,M.; Schkolnik, V.; Leykauf, B.; Schilling, Manuel; Wziontek, H.; Scherneck, H.-G.; Müller, J.; Peters, A. (Bristol : Institute of Physics Publishing, 2016)
    Changes of surface gravity on Earth are of great interest in geodesy, earth sciences and natural resource exploration. They are indicative of Earth system's mass redistributions and vertical surface motion, and are usually ...
  • Schwarze, Thomas S.; Fernández Barranco, G.; Penkert, D.; Gerberding, Oliver; Heinzel, Gerhard; Danzmann, Karsten (Bristol : Institute of Physics Publishing, 2016)
    The planned spaceborne gravitational wave detector LISA will allow the detection of gravitational waves at frequencies between 0.1 mHz and 1 Hz. A breadboard model for the metrology system aka the phasemeter was developed ...
  • Flury, Jakob (Bristol : Institute of Physics Publishing, 2016)
    Quantum metrology enables new applications in geodesy, including relativistic geodesy. The recent progress in optical atomic clocks and in long-distance frequency transfer by optical fiber together pave the way for using ...
