Andreas Kemna,Andrew Binley,Giorgio Cassiani,Ernst Niederleithinger,André Revil,André Revil,Lee Slater,Kenneth H. Williams,Adrián Flores Orozco,Franz-Hubert Haegel,Andreas Hördt,Sabine Kruschwitz,Virginie Leroux,K. Titov,Egon Zimmermann +14 more
TL;DR: In this paper, the authors summarize the state of the art in spectral induced polarization (SIP) for near-surface applications and describe which aspects still represent open issues and should be the focus of future research efforts.

Method and apparatus for rapid tomographic measurements of the electrical conductivity distribution of a sample
TL;DR: In this paper, a method and apparatus for the rapid tomographic measurement of conductivity distribution in a sample in which current excitations or voltage excitation is applied to the sample via electrodes or the like and potential differences or magnetic field strengths association with those excitation fields are measured and analyzed, e.g. by a Fourier analysis.
Journal ArticleDOI
A high-accuracy impedance spectrometer for measuring sediments with low polarizability
Egon Zimmermann,Andreas Kemna,Joachim Berwix,Walter Glaas,H.-M. Münch,Johan Alexander Huisman +5 more
TL;DR: In this paper, the authors present a new impedance spectrometer based on the four-point measurement method and offers a measurement range from 1 mHz to 45 kHz with a phase accuracy better than 0.1 mrad.
Journal ArticleDOI
EIT measurement system with high phase accuracy for the imaging of spectral induced polarization properties of soils and sediments
TL;DR: In this article, a spectral EIT data acquisition system for laboratory applications is presented, which operates in the frequency range from 1 mHz to 45 kHz and leads to significantly improved phase images, particularly for higher measurement frequencies.
Journal ArticleDOI
Pulse shape discrimination of LSO and LuYAP scintillators for depth of interaction detection in PET
TL;DR: In this article, the depth of interaction information in a positron emission tomography scanner using phoswich detectors is identified from the pulse shape of the corresponding scintillator material.
