Abstract: The invention relates to a device for checking the authenticity of an anti-forgery marking with colours which change depending on the angle of observation, comprising a) several first light sources, emitting in a given spectral range, whereby the light sources are different from each other with regard to the wavelength of the emission maximum thereof and the first light sources (1) are housed in a housing (5) such as to irradiate the surface (O), with the housing (5) placed thereon, at a given first angle ( alpha 1), b) a first means (2) for measuring the intensity of the light reflected from the surface (O) arranged at a second angle ( alpha 2) and c) a means (7) for the automatic comparison of measured intensities with the reference intensities stored for at least one given colour for each light source (1).

Abstract translation: 设备用于确定性挖掘面（O），其中，所述颜色上的颜色或颜色与观察角度观察到的，而有所不同。 该装置具有多个光源（1）在给定的光谱范围内发射光，但具有不同的波长。 源被包含在一个壳体（5）所以没有它们的光入射在所述表面上的第一角度（α1）。 检测手段，（2）检测的反射光的第二角度（α-2），同时提供了用于参考的强度或用于颜色空间坐标的计算所测量的强度的自动比较。 该装置可以通过提供另外的光源（3）发射的第三角度（approximatelyB1）被扩大，而第二检测器在第四角度（approximatelyB2）检测光。 独立claimsoft是用于检测在表面上的颜色或颜色，其中所述颜色变化依赖于观察角度的方法制造。
