Abstract

A radiation detector is disclosed with a detector arrangement, which has a plurality of detector elements, by means of which a detector signal is obtained during operation of the radiation detector, and with a control device, wherein the detector elements each have a spectral sensitivity distribution, and are suited for generating signals, at least one detector element comprises a compound semiconductor material, and this detector element is designed for detecting radiation in the visible spectral region, the radiation detector is designed such that the sensitivity distributions of the detector elements are used to form different spectral sensitivity channels of the radiation detector, a channel signal assigned to the respective sensitivity channel can be generated in these sensitivity channels using the detector elements, and the control device is designed such that the contributions of different channel signals to the detector signal of the radiation detector are differently controlled.
