Abstract
A sensor () serves for capturing a moving material web (). It has at least one light source () and at least one light detector (). At least one polarization element () is provided between the two, which polarization element influences polarization properties of the light transmitted by the polarization element () as a function of an electric field. Markings such as for example metal strips () in the material web () can thus be captured in the light detector () without problem.
