  • Patent number: 12344022
    Abstract: An optically variable security element is provided for protecting objects of value. The reflective area region includes two independent relief structures, which are arranged at different levels in the z-direction and form a lower-level relief structure and a higher-level relief structure. The higher-level relief structure is supplied with a first reflection-enhancing coating following the relief profile, and the lower-level relief structure is supplied with a second reflection-enhancing coating following the relief profile. The first reflection-enhancing coating is formed in the visible spectral range with a reflection and transmission in the visible spectral range, so that the higher-level relief structure shows a first optically variable effect in a first color, and the lower-level relief structure shows a second optically variable effect through the first reflection-enhancing coating, wherein the second optically variable effect shows itself in a second, different color.

  • Patent number: 12136310
    Abstract: An optical sensor for examining value documents, such that at a point in time before the check of the value documents, a self-test of the optical sensor is carried out, during which the light sources thereof are switched on, and, with the aid of monitor elements, the respective light intensity of the light source assigned to the respective monitor element is detected which impinges on the respective monitor element at the time of the self-test. During the check of a value document following the self-test, the light sources illuminate the value document, and measured values are recorded. The recorded measured values are then corrected with the aid of the light intensities detected by the monitor elements at the time of the self-test to take into account a change in the light intensity emitted by the light sources that occurs in the course of the service life of the light sources.
