    摘要: A system (10) is provided for performing first-order authentication of articles marked with indicia (30) discernible in visible, ultraviolet, or infrared light or tagged with UV- or IR-sensitive chemicals. The first-order authentication system provides reliable visual authentication by providing for juxtaposition of the article-under-test (20) with a known reference-standard sample-specimen (90, 100, or 300), while the article-under-test (20) is illuminated by a suitable source (65 or 250) of radiation in the visible, ultraviolet, or infrared portions of the electromagnetic spectrum. Thus, the system (10) facilitates comparison to differentiate a genuine article from a counterfeit article with first-order accuracy but at a substantially lower cost than that of automated authentication systems. Additionally, the system can be used in both portable and desk top embodiments. The system preferably has optional interchangeable holders (140 or 400) for various articles-under-test as well as an optional interchangeable holder (115) for various reference-standard sample-specimens. Some embodiments utilize structures incorporating split-image optics (200), superposed-image optics, and/or a blink-comparator.

    摘要: Detecting counterfeit bank notes is achieved by directing ultraviolet light at a sample from a source (2) and measuring the level of ultraviolet light reflected from the sample using a first photocell (104) and the amount of fluorescent light generated by the sample using a second photocell (106). The detected levels are compared with reference levels and only if both reflective and fluorescent criteria are satisfied is the note declared genuine. The sample, during test, is supported on a glass plate (102). The apparatus uses the value of the intensity of light reflected from the glass plate (in the absence of a sample) as a basis for producing at least one reference level against which a subsequent comparison can be made.
