  • Ley, Peer-Phillip; Held, Marcel Philipp; Lachmayer, Roland (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    Highly adaptive light sources such as LED arrays have been surpassing conventional light sources (halogen, xenon) for automotive applications. Individual LED arrangements within the array, high durability and low energy ...
  • Held, Marcel Philipp; Ley, Peer-Phillip; Lachmayer, Roland (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    High-resolution vehicle headlamps represent a future-oriented technology that increases traffic safety and driving comfort in the dark. A further development to current matrix beam headlamps are LED-based pixellight systems ...
  • 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. ...
  • Kamata, N.; Klausing, H.; Fedler, F.; Mistele, D.; Aderhold, J.; Semchinova, O.K.; Graul, J.; Someya, T.; Arakawa, Y. (Cambridge : Cambridge University Press, 2004)
    In order to improve the crystal quality of GaN-based light emitting devices, photoluminescence (PL) characterization of below-gap states in plasma assisted MBE-grown GaN/AlGaN quantum well (QW) structures has been done by ...
  • Held, Marcel Philipp; Lachmayer, Roland (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    High-resolution vehicle headlamps represent a future-oriented technology that can be used to increase traffic safety and driving comfort. As a further development to the current Matrix Beam headlamps, LED-based pixel light ...
  • 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 ...
  • Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    A new family of lighting products is developed as laser diodes replace LEDs in the remote phosphor configuration. The resulting lighting systems, also known as laser-excited remote phosphor systems, exhibit advanced ...
  • Lachmayer, Roland; Kloppenburg, Gerolf; Wolf, Alexander (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Bright white light sources are of significant importance for automotive front lighting systems. Todays upper class vehicles mainly use HID or LED as light source. As a further step in this development laser diode based ...
  • Rizvi, Sadiq; Ley, Peer-Phillip; Knöchelmann, Marvin; Lachmayer, Roland (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    Research reveals that visual information forms the major portion of the received data for driving. At night -owing to the, sometimes scarcity, sometime inhomogeneity of light- the human physiology and psychology experiences ...
  • Rizvi, Sadiq; Knöchelmann, Marvin; Ley, Peer-Phillip; Lachmayer, Roland (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    HID, LED and laser-based high resolution automotive headlamps, as of late known as pixel light systems', are at the forefront of the developing technologies paving the way for autonomous driving. In addition to light ...
  • Lachmayer, Roland; Kloppenburg, Gerolf; Stephan, Serge (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Bright white light sources are of significant importance for automotive front lighting systems. Today's upper class systems mainly use HID or LED light sources. As a further step laser diode based systems offer a high ...
