    • An apparatus for checking bank notes which scans the bank notes to be checked by means of a semiconductor array, including two linear semiconductor arrays formed of at least three layers which are sensitive to light of different wave-lengths, a first linear semiconductor array scanning the bank notes in a defined range of spectral sensitivity of the semiconductor (e.g. in the visible range), and a second linear semiconductor array scanning the bank notes in a range different therefrom (e.g. of invisible infrared light). From the signals of the two arrays a color image of the bank note and at least one image in the range of invisible light are obtained by suitable combination.
    • 一种用于检查纸币的装置,其通过半导体阵列扫描要检查的纸币,包括由对不同波长的光敏感的至少三层形成的两个线性半导体阵列,第一线性半导体阵列扫描 在半导体的光谱灵敏度的限定范围内(例如,在可见光范围内)的钞票和在与其不同的范围(例如,不可见的红外光)扫描纸币的第二线性半导体阵列)。 从两个阵列的信号中,通过适当的组合获得钞票的彩色图像和不可见光范围内的至少一个图像。

    • The invention relates to an apparatus for checking bank notes which scans the bank notes to be checked by means of a semiconductor array. The inventive apparatus for checking bank notes has two linear semiconductor arrays formed of at least three layers which are sensitive to light of different wavelengths, a first linear semiconductor array scanning the bank notes in a defined range of spectral sensitivity of the semiconductor (e.g. in the visible range), and a second linear semiconductor array scanning the bank notes in a range different therefrom (e.g. of invisible infrared light). From the signals of the two arrays a color image of the bank note and at least one image in the range of invisible light are obtained by suitable combination. The inventive apparatus has the advantage that it can be realized simply and economically, and provides good check results since it avoids artifacts which can be caused for example by parallactic errors.
    • 本发明涉及一种用于检查纸币的装置,该钞票扫描通过半导体阵列检查的钞票。 用于检查纸币的本发明的装置具有由对不同波长的光敏感的至少三层形成的两个线性半导体阵列,第一线性半导体阵列在半导体的光谱灵敏度的限定范围内扫描钞票(例如, 可见光范围)和第二线性半导体阵列扫描与其不同的范围(例如不可见的红外光)的钞票。 从两个阵列的信号中,通过适当的组合获得钞票的彩色图像和不可见光范围内的至少一个图像。 本发明的装置具有可以简单和经济地实现的优点,并且提供良好的检查结果,因为它避免了可能由于例如由于失配误差引起的伪影。
