Original Kurzfassung:
Electrical resistance tomography (ERT) is a widely used method for measuring and localizing properties attributable to changes in conductivity in a region. Electrodes attached to the boundary of the region are used for excitation and measurement. An alternating current source is used for excitation. The aim is to reconstruct the change in conductivity from the voltage measurements taken during excitation. The accuracy of the electronics is a decisive factor. The quality of the reconstructed images depends on it. A major di culty is the fact that changes in conductivity often lead to relatively small voltage changes at the boundary. The statistical and deterministic errors of a self-developed measurement electronics were determined by analyzing the measurements taken. This allowed us to determine the measurement uncertainty of the system.
