Abstract

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.

Claims

AMENDED CLAIMS[received by the International Bureau on 8 July 1994 (08.07.94); original claim 1 amended; remaining claims unchanged (1 page)]
1. Apparatus for detecting counterfeit objects comprising means for illuminating the object with light within a first wavelength band, a detector for detecting reflected light from said object having a first wavelength within said first wavelength band and for detecting light having a second wavelength within a second wavelength band different from said first wavelength band, said second wavelength band including wavelengths at which counterfeit objects may fluoresce when exposed to light in said first wavelength band, comparison means for comparing the output of the detector with at least one reference level directly related to the output of the illuminating means and decision means for deciding, based on said comparison whether said object is counterfeit or not and providing an appropriate indication.
2. Apparatus according to Claim 1 wherein said first wavelength band width is the ultraviolet light wavelength band width and said second wavelength band width is 400 to 500 nm.
3. Apparatus according to Claim 1 or to Claim 2 wherein said detector comprises first and second photocells each positioned to receive light from a said object respectively through a first optical filter only passing light in said first wavelength band and through a second optical filter only passing light in said second wavelength band.
4. Apparatus according to any one of Claims 1 to 3 including a glass plate for supporting a said object on one side thereof with the illumination means and the detection means being located on the other side thereof and directed at the object through said glass plate.
5. Apparatus according to Claim 4 as dependant upon Claim 3 including reference means for storing a first reference level which is a function of the light reflected
