Classification: CPC G | IPC G

Claim 0:
1. An inspection arrangement for a fluorescence-based inspection of a laminate product which is composed of a plurality of layers, one layer containing at least one fluorophore having an excitation spectrum and an emission spectrum, the inspection arrangement comprising:
a radiation source for generating a first electromagnetic radiation in a first wavelength range containing the excitation spectrum of the at least one fluorophore, wherein the first radiation source is configured as a UV lamp, as UV light or as a black light lamp so that the first electromagnetic radiation is UV-A radiation, and a second electromagnetic radiation in a second wavelength range containing the emission spectrum of the at least one fluorophore;
an imaging device for generating images of an inspection area in which the laminate product is arranged; and
an image data processing device for image processing of the images,
wherein,
the inspection arrangement is designed to capture with the imaging device at least one fluorescence image of the inspection area irradiated with the first electromagnetic radiation, and to capture with the imaging device at least one reference image of the inspection area irradiated with the second electromagnetic radiation,
the image data processing device is configured to generate a correction image based on the at least one fluorescence image and the at least one reference image;
the first wavelength range does not overlap with the second wavelength range, and
the generation by the radiation source of the first electromagnetic radiation does not occur simultaneously with the generation by the radiation source of the second electromagnetic radiation.
