Abstract

The invention refers to a system for analyzing a document. Each of two measurement arrangements includes two components being a radiation source and a radiation detector, respectively. The two measurement arrangements provide measurement data and differ from each other with regard to a measurement principle, a kind of radiation source, a kind of radiation detector, a kind of relative movement between the document and a component, a kind of relative arrangement of the two components to each other, a kind of emitted radiation, a kind of received radiation or a kind of processing information about radiation emitted by the respective radiation source and/or about radiation received by the respective radiation detector. An evaluator provides data based on the measurement data. The invention also refers to a corresponding method.
