    • 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账单来对货币账单进行伪造判定。 真正的货币账单包括用油墨印刷的标记,其在两个不同波长处对红外照明的响应类似。 为了将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光照亮。 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光照射测试货币账单。 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不是基本相同,则测试货币钞票被识别为可疑伪钞。
