Abstract
In one aspect, a validation apparatus comprises a light source capable of emitting a broadband spectrum of light for illuminating an item of currency. The validation apparatus also includes a receiver configured to receive light emitted from the light source. In another aspect, the validation apparatus also includes a transportation unit configured to transport the item of currency within the validation apparatus. In a further aspect, the validation apparatus also includes a processor configured to reconstruct a spectral response of the item of current. In this design, the light received by the receiver comprises at least a portion of light reflected by or transmitted through the item of currency.
Claims38
A validation apparatus comprising:
- a light source capable of emitting a broadband spectrum of light for illuminating an item of currency;
- a receiver configured to receive light emitted from the light source, wherein the received light comprises at least a portion of light reflected by or transmitted through the item of currency;
- a transportation unit configured to transport the item of currency within the validation apparatus;
- and
- a processor configured to reconstruct a spectral response of the item of currency.
A method of validating an item of currency comprising the steps of:
- transporting the item of currency within the validation apparatus;
- emitting a broadband spectrum of light to illuminate an item of currency at at least one spot;
- receiving at least a portion of the light reflected by or transmitted through the item of currency emitted from the light source;
- and
- reconstructing via a processor a spectral response of the item of currency.
