Abstract (en)
[origin: WO2015022394A1] Method and device for checking a security element (4) of a security document, wherein the security element (4) can contain at least one substance (5) with optically variable properties, comprising the following method steps:- illuminating the security element (4) with at least one predetermined illumination parameter, - filtering the light reflected from the security element into a first component (RLp) having a first polarization, - determining an intensity (I) of the first component (RLp) of reflected light which is reflected at a reflection angle (φR), for at least one reflection angle (φR), verification of a presence of a substance (5) having optically variable properties as a function of the intensity (I) of the first component (RLp).
