    • The invention relates to a method for checking value documents by which the similarity of the intensity spectrum of a value document to be checked to a reference spectrum can be tested. To check the similarity of the intensity spectrum recorded from the value document to be checked to the reference spectrum, not the recorded intensity spectrum itself is compared with the reference spectrum, but rather a corrected intensity spectrum adapted to the reference spectrum, which arises from the recorded intensity spectrum by a linear correction. The correction parameters of the linear correction function are ascertained by adapting the linearly corrected intensity spectrum to the reference spectrum. Through the adapting it is achieved that fluctuations of the recorded intensity spectrum that are due to measuring technology are compensated at least partly.
    • 本发明涉及一种用于检查价值文件的方法,通过该方法可以测试待检查的价值文档的强度谱与参考频谱的相似度。 为了检查从要检查的值文档记录的强度谱与参考光谱的相似性,不将记录的强度谱本身与参考光谱进行比较,而是与适用于参考光谱的校正强度谱相关, 通过线性校正记录强度谱。 通过将线性校正的强度谱适应于参考光谱来确定线性校正函数的校正参数。 通过适应,实现由测量技术引起的记录强度谱的波动至少部分被补偿。

    • A spectral sensor for inspecting value documents, includes an illumination device for illuminating the value document, imaging optics and a detection device. The illumination device contains a plurality of light sources with emission spectra that differ from one another, and which are switched on and off in succession, to illuminate a region of the value document with an illumination sequence consisting of light pulses with different emission spectra. One measured value is detected for each of the light pulses to record the spectral intensity distribution of the detected light. The plurality of light sources cover a section of the near infra-red spectral range and/or a section of the visible spectral range in such a way that the spectral sensor can record a spectral intensity distribution in the section of the near infra-red spectral range and/or in the section of the visible spectral range.
