A sensing system comprising a light filtering apparatus configured to pass a first wavelength of light corresponding to an emission spectrum characteristic of Mercury. The sensing system comprises a sensor configured to receive light passed by the light filtering apparatus and produce a sensor response that is indicative of the light passed by the light filtering apparatus. The sensing system comprises a processor configured to use the sensor response to distinguish between light emitted by a fluorescent light source and light emitted by a light emitting diode.

Sensing system

The optical sensor package comprises an optical sensor device with a sensor element arranged inside a housing comprising a cap. A diffuser is arranged in an aperture of the cap opposite the sensor element and prolongs the cap in the aperture or closes the aperture. The method comprises forming a cap with an aperture, arranging a diffusing material in the aperture, thus forming a diffuser, and after forming the diffuser, arranging an optical sensor device with a sensor element inside a housing that includes the cap, such that the sensor element is opposite the diffuser.

Optical sensor package and method of producing same

A security element and a value document having such a security element in the form of a strip having a first and second polymer layer are shown, having a visually recognizable halftone printed image, which is luminescent under UV radiation, between the first and second layer, wherein the halftone printed image has an opacity and forms at least one imprint area having a boundary contour within the security element. To increase the forgery protection, it is proposed that at least one of the two polymer layers have an opacity at least in the region of the boundary contour of the imprint area and be adapted in its opacity to the opacity of the imprint area, in order to diminish the visual recognizability of the boundary contour of the imprint area of the luminescent halftone printed image on the security element.

Security element and value document having this security element

A value document having a security element in the form of a strip with a first polymer layer which comprises at least one embossed diffraction structure, having at least one reflection layer which visually interacts with the diffraction structure in order to form a reflection hologram as the first visually recognisable security feature, and having at least one imprint which is luminescent under UV radiation and which forms a second security feature that is visually recognisable under UV light, wherein the reflection hologram comprises at least one see-through region on the second security feature. In order to increase the level of protection against forgery of the security element, the luminescent imprint comprises a halftone print image, and the see-through region is formed by at least one recess in the reflection layer and by the polymer layer which is free in this region of the recess from the diffraction structure at least above the halftone print image of the imprint.

Security element and value document having said security element

The invention relates to a security element, comprising a thermoplastic or photo-sensitive replication lacquer layer, non-periodic randomly arranged (randomized) structures in the sub-micrometer range being incorporated into the replication lacquer layer and having an angle-independent optical effect, such as a color effect, and to a method for the production thereof and to the use thereof.
