  • Patent number: 8927072
    Abstract: An optically variable security device comprises a photonic crystal which, upon receipt of incident light, generates a first optical effect, and which, when the device is subjected-to-an external stimulus, generates a second optical effect that is different from the first optical effect. At least one of the first and second optical effects is an optically variable effect observable over a set of directions. The optically variable effect is caused by the light being selectively reflected or transmitted by the crystal.

  • Patent number: 8908276
    Abstract: A moiré magnification device includes a transparent substrate carrying: a regular array of micro-focusing elements, that define a focal plane, on a first surface; a corresponding first array of microimage elements in a first color located in a plane substantially coincident with the focal plane; and a corresponding second array of microimage elements, in a second color, located in a plane substantially coincident with the focal plane. The pitches of the micro-focusing elements and first and second arrays and their relative locations are such that the array of micro-focusing elements cooperates with each of the first and second arrays to generate magnified versions of the microimage elements due to the moiré effect. The magnified version of the first array is viewed against a background defined by the magnified version of the second array, the first array exhibiting movement relative to the background when the device is tilted.

  • Patent number: 8820793
    Abstract: Improvements in security devices are provided that are used for authenticating or security applications. The security device includes a first color-shifting layer and a second color-shifting layer, which exhibits different reflective characteristics to the first color-shifting layer. A partial first light absorbing layer is between first surfaces of the first and second color-shifting layers and a second light absorbing layer applied to a second surface of the second color-shifting layer. The color of the partial first absorbing layer is selected to substantially match the color of light reflected at a normal angle of incidence by the combination of the second color-shifting layer and the second absorbing layer.

  • Publication number: 20140226212
    Abstract: The present invention relates to improvements in security devices that can be used in various authenticating or security applications, and in particular to an optically variable security device which can be viewed under low light conditions. The security device comprises a light deflection structure having a first side and a second opposing side. A colourshifting layer is applied to the first side of the light deflection structure and a reflection layer is applied to at least a first region of the second side of the light deflection structure so as to provide a strong reflection in a direction substantially parallel to the incident light source when the direction of the incident light is at an angle away from the normal to the security device. The security device has at least one second region in which the reflection layer is absent, said first and second regions defining indicia.

  • Publication number: 20140191500
    Abstract: A security device has a lenticular device including an array of lenticular focusing elements; a corresponding array of image strips sets, the sets having substantially the same periodicity as, or an integral multiple of the periodicity of, the array of focusing elements. The strips are formed and the focusing elements located relative to the strips such that at each of a plurality of viewing angles, a respective one strip from each set is viewed in response to incident light falling on a respective focusing element. The strips are constructed such that the device presents a cyclically repeating sequence of images as the device is viewed at successive viewing angles, the image sequence including a change in form of an image between a first and second form and then a reversal of the sequence back to the first form, the combined image sequences presenting a contiguous variation in the image form.

  • Patent number: 8696032
    Abstract: A security device comprises a substrate having a transparent region (1). At least one optical element (2, 3) is provided in part of the transparent region, the optical element causing an incident off-axis light beam transmitted through the optical element to be redirected away from a line parallel with the incident light beam whereby when the device is viewed in transmission directly against a backlight, the presence of the optical element cannot be discerned but when the device is moved relative to the backlight such that lines of sight from the viewer to the transparent region and from the transparent region to the backlight form an obtuse angle (?) at which redirected light is visible to the viewer, a contrast is viewed between the part of the transparent region including the optical element and another part of the transparent region.

The holographic security device generates two or more holographic images viewed from separate and/or overlapping viewing directions around the device and seen by tilting the device, and each particular holographic image in a viewing direction is generated by the diffractive image generating structure associated with one set of interleaved lines. The first diffractive image generating structure has been formed to have a diffuse diffractive replay and the second diffractive image generating structure has been formed to have a non-diffuse or specular diffractive replay.
