    • A counterfeit determination is made with respect to currency bills by illuminating the currency bill with multiple wavelengths of light. Genuine currency bills include indicia printed with an ink that responds similarly to infra-red illumination at two different wavelengths. To identify a test currency as a suspect counterfeit, the bill is first illuminated with infra-red light at a first wavelength. A measurement is then made of a first reflected light response from the first illumination. The test currency bill is then second illuminated with infra-red light at a second wavelength. A measurement is then made of a second reflected light response from the second illumination. The first and second reflected light responses are then compared, and the test currency bill is identified as a suspect counterfeit if the first and second reflected light responses are not substantially the same.
    • 通过用多个波长的光照亮货币单据,对货币票据进行伪造确定。 真正的货币单据包括印有墨水的标记,其类似于两种不同波长的红外照明。 为了将一种测试货币识别为可疑的假币,该钞票首先以第一波长的红外线照亮。 然后测量来自第一照明的第一反射光响应。 然后用第二波长的红外线照射测试货币单据。 然后测量来自第二照明的第二反射光响应。 然后比较第一和第二反射光响应,并且如果第一和第二反射光响应基本不相同,则将测试货币单据识别为可疑假冒伪劣。
