| 摘要 |
The invention relates to a device for recognizing a document that has a security feature having wavelength conversion properties, comprising a light-producing apparatus (101), which is designed to illuminate the security feature with excitation light so that the security feature emits light, an image-sensing apparatus (103), which is designed to sense a light emitted by the security feature in response to the excitation light in order to obtain an emission image, wherein the image-sensing apparatus is also designed to sense light emitted by the security feature in response to a reference light in order to obtain a reference image, and a processor (105), which is designed to recognize the document on the basis of the emission image and the reference image. |
