Contactless electromagnetic measuring system using conventional calibration algorithms to determine scattering parameters

Zelder, T.; Rabe, H.; Eul, H. (Göttingen : Copernicus GmbH, 2007)

In this paper, a contactless measuring system for the determination of the S-parameters of planar circuits is presented. With a contactless measuring system it is possible to characterise a device-under-test (DUT) embedded ...
Contactless vector network analysis using diversity calibration with capacitive and inductive coupled probes

Zelder, T.; Rolfes, I.; Eul, H. (Göttingen : Copernicus GmbH, 2007)

Contactless vector network analysis based on a diversity calibration is investigated for the measurement of embedded devices in planar circuits. Conventional contactless measurement systems based on two probes for each ...
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 ...
Numerical modeling of a MEMS actuator considering several magnetic force calculation methods

Preisner, Thomas; Bolzmacher, Christian; Gerber, Andreas; Bauer, Karin; Quandt, Eckhard; Mathis, Wolfgang (Bingley : Emerald Group Publishing Ltd., 2011)

Purpose: The purpose of this paper is to investigate the accuracy of different force calculation methods and their impact on mechanical deformations. For this purpose, a micrometer scaled actuator is considered, which ...
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 ...
Radar distance measurements in circular waveguides involving intermodal dispersion effects

Denicke, Eckhard; Armbrecht, Gunnar; Rolfes, Ilona (Cambridge : Cambridge University Press, 2010)

This contribution deals with guided radar distance measurements in the field of industrial tank level control. The aim is to achieve a submillimeter gauging accuracy even when conducting the measurement within a highly ...
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 ...
