  • 3D geometry measurement of hot cylindric specimen using structured light 
    Quentin, Lorenz; Beermann, Rüdiger; Pösch, Andreas; Reithmeier, Eduard; Kästner, Markus (Bellingham, Wash. : SPIE, 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 ...
  • Comparison of LASER and LED illumination for fiber optic fringe projection 
    Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 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. ...
  • Endoscopic fringe projection for in-situ inspection of a sheet-bulk metal forming process 
    Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 2015)
    Sheet-bulk metal forming is a new production process capable of performing deep-drawing and massive forming steps in a single operation. However, due to the high forming forces of the forming process, continuous process ...
  • Multiscale optical inspection systems for the regeneration of complex capital goods 
    Schlobohm, Jochen; Li, Yinan; Pösch, Andreas; Langmann, Benjamin; Kästner, Markus; Reithmeier, Eduard (Amsterdam : Elsevier, 2014)
    The inspection of capital goods with complex geometries is a challenging task due to the limited maneuvering and measuring space available. We developed a set of optical measurement systems for the inline inspection of ...
  • On the development of a low-cost rigid borescopic fringe projection system 
    Schlobohm, Jochen; Pösch, Andreas; Kästner, Markus; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 2015)
    Examining the geometry of complex industrial free form objects, like a blade integrated disk (blisk) of a jet engine compressor, is currently subject to research. High measurement precision and speed are required and the ...
  • A raspberry pi based portable endoscopic 3D measurement system 
    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 ...
  • Two-step phase shifting in fringe projection: Modeling and analysis 
    Mao, Jiaqi; Yin, Yongkai; Meng, Xiangfeng; Yang, Xiulun; Lu, Lei; Li, Dechun; Pape, Christian; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 2018)
    This work proposes a two-step phase-shifting algorithm as an improvement of fringe projection profilometry. Considering the working process of fringe projection, the captured fringe image is formulated with two variables, ...
