  • Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The inspection of functional elements is a crucial part of modern production cycles. However, with higher integration of production machinery and products, the accessibility for measurement systems is more and more limited. ...
  • Singh, Amrit Pal; Ast, Stefan; Mehmet, Moritz; Vahlbruch, Henning; Schnabel, Roman (Washington, DC : OSA - The Optical Society, 2019)
    Continuous-wave (cw) squeezed states of light have applications in sensing, metrology and secure communication. In recent decades their efficient generation has been based on parametric down-conversion, which requires ...
  • Schlichting, S.; Willemsen, Thomas; Ehlers, H.; Morgner, Uwe; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    In the presented work a fast frequency domain measurement system to determine group delay (GD) and group delay dispersion (GDD) of optical coatings is proposed. The measurements are performed in situ directly on moving ...
  • Suar, Monali; Melchert, Oliver; Rahlves, Maik; Roth, Bernhard (Washington, DC : OSA - The Optical Society, 2019)
    The realization of optical interconnects between multimode (MM) optical fibers and waveguides based on a self-writing process in photopolymer media represents an efficient approach for fast and easy-to-implement connection ...
  • Nolte, Lena; Antonopoulos, Georgios C.; Heisterkamp, Alexander; Ripken, Tammo; Meyer, Heiko (Bellingham, WA : S P I E - International Society for Optical Engineering, 2018)
    Scanning laser optical tomography (SLOT) is a 3D imaging technique, based on the principle of computed tomography to visualize samples up to magnitude of several centimeters. Intrinsic contrast mechanisms as absorption, ...
  • Rezem, Maher; Kelb, Christian; Günther, Axel; Rahlves, Maik; Reithmeier, Eduard; Roth, Bernhard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Micro-optical sensors based on optical waveguides are widely used to measure temperature, force and strain but also to detect biological and chemical substances such as explosives or toxins. While optical micro-sensors ...
  • Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    The development of laser-based lighting systems has been the latest step towards a revolution in illumination technology brought about by solid-state lighting. Laser-activated remote phosphor systems produce white light ...
