Problems solved by technology

[0002] The supply of counterfeit goods in a given market results in a loss of revenue for the manufacturers of the corresponding genuine goods, as well as for the government when taxing those goods
End users are adversely affected by counterfeit goods as a result of being supplied with inferior products, which may even be harmful to the health of end users in the case of certain products (such as where pharmaceuticals are counterfeit subjects, etc.)
As a result, the goodwill of the manufacturer of high-quality authentic products will suffer.

example 1

[0061] - Example 1 : especially for transmission gratings mounted in front of the objective (see also in this regard Figure 4 and Figure 23 ), a Thorlabs #GT13-06V made of Schott B270 glass with a groove density of 600 lines / mm (l / mm), a blaze angle of 28.7°, and a size of 12.7×12.7×3mm (from the headquarters in New Jersey, USA) can be used Thorlabs, Inc. of Newton, CA).

[0062] - Example 2 : especially for transmission gratings mounted between the objective lens and the image sensor (see also in this regard Figure 5 , Figure 6 and Figure 24 ), a Richardson grating 340056TB07-775R (from Newport Corporation headquartered in Rochester, New York, USA) with a groove density of 360 l / mm, a blaze angle of 21° and a size of 12.7×12.7×3 mm can be used.

[0063] - Example 3 : Especially for back-mounted gratings for extended field of view, Thorlabs #GTU13-06 with a groove density of 600l / mm, a blaze angle of 22° and a size of 12.7×12.7×2mm can be used.

Embodiment

[0223] Embodiment (X4). The imaging system (200) of embodiment (X2) or (X3), wherein the imaging device is a handheld device.

[0224] Embodiment (X7). The imaging system (200) according to any one of claims 1 to 3 and embodiments (X2) to (X4), wherein,

[0225] The imaging system (200) is configured for imaging the dispersive electromagnetic radiation (50) after the image sensor arrangement (60) over a plurality of illumination time periods (t1, t2, ..., tn) , generating the authenticity measure; and

[0226] Generating the authenticity measure includes:

[0227] For each irradiation time period (t i ), at least according to the irradiation time period (t i ) to generate an intermediate measure of authenticity (k i ), said portion of said reference spectral information is associated with how said object (10) was irradiated during said illumination time period (ti); and

[0228] Based on the generated multiple authenticity intermediate measures (k 1 ,k 2 ,...,k n ) to ...

Abstract

An imaging system (200) for generating an authenticity measure of an object (10) includes a dispersive imaging arrangement (30) and an image sensor arrangement (60). Positioning the dispersive imaging arrangement (30) and the image sensor arrangement (60) such that, in the event that electromagnetic radiation (20) from the object (10) illuminates the dispersive imaging arrangement (30), the electromagnetic radiation is dispersed and the image sensor arrangement (60) Imaging the electromagnetic radiation. The imaging system (200) is then configured to generate an authenticity measure of the object (10) based at least on a relationship between the imaged dispersive electromagnetic radiation and reference spectral information. The invention also relates to an imaging method, a computer program, a computer program product and a storage medium.

Description

technical field [0001] The invention relates to a system for generating an authenticity measure of an object. The invention also relates to a method, a computer program, a computer program product and a storage medium for the same purpose. Background technique [0002] The availability of counterfeit goods in a particular market results in a loss of revenue for the manufacturers of the corresponding genuine goods, as well as for governments when taxing those goods. End users are adversely affected by counterfeit goods by being supplied with inferior products, which may even be detrimental to the health of end users for certain products (such as the case of pharmaceuticals being the subject of counterfeit, etc.). As a result, the goodwill of the manufacturer of high-quality authentic products will suffer. [0003] In the prior art, for example alcoholic and non-alcoholic beverages (beer, wine, spirits, soft drinks, etc.), tobacco products (cigarettes, cigars, loose tobacco,...
