Claims (14)

It ’s a micro-optical security device.
(I) Focusing element array (101),
(Ii) In close proximity to the focused element array such that at least one composite image is projected by the image projection system when at least a portion of the image icon element array is viewed through at least a portion of the focused element array. Includes the image icon element array (103) arranged and (iii) a control pattern element array (203) integrated across the image icon element array.
With the image projection system
A set of target images (310', 310 ") comprising at least one target image, which is one of the at least one composite image projected by the image projection system.
Includes at least one reward image (350),
A micro-optical security device, wherein the micro- optical security device provides a target effect in which the target image is spatially adjusted to match the expression of the at least one reward image in a predetermined alignment phase. A claim that the control pattern element array includes in-phase and out-of-phase portions, and when the focusing element array focuses on the in-phase portion, substantially all parts of the control pattern element array are in focus. The micro optical security device according to 1. When the control pattern element array removes a portion of the image icon element array, or when the micro-optical security device is seen in the predetermined alignment phase, the control pattern element of the control pattern element array is said to be said. The micro-optical security device of claim 1 , comprising a window in which a reward image appears . Claim 1 that at least two of the target images are composite images projected by the image projection system and at least one of the reward images is a composite image projected by the image projection system. The micro optical security device described in . At least one of the target images comprises an optical image and at least one of the reward images is at least one of a composite image or an optical image, or at least one of the target images. The micro-optical security device of claim 1 , wherein one has a dynamic effect and at least one of the reward images has a dynamic effect . The target image is completely hidden in the predetermined alignment phase, the reward image is completely hidden outside the predetermined alignment phase, and the focusing element array focuses on the in-phase portion of the control pattern element array. The micro-optical security device according to claim 1, wherein the reward image is displayed only when the reward image is present . Claimed that the spatial adjustment between the target images is based on at least one of a predetermined position of the target image, a predetermined color change of the target image, or a predetermined resizing of the target image. The micro optical security device according to 1 . The focusing element of the focusing element array is non-cylindrical, the image icon element of the image icon element array is a recess filled with pigment ink, and the control pattern element of the control pattern element array is the image. Arranged within an array of removed portions of the icon element, said when the set of target images comprises two sets of synthetic images with dynamic effects and the target images overlap in said predetermined alignment phase. The micro-optical security device of claim 1, wherein the set of the two composite images is spatially adjusted so that at least one reward image is expressed and the target image is hidden . The micro-optical security device according to claim 1, wherein the focusing element of the focusing element array is embedded in an optical film . The micro-optical security of claim 1, wherein the image icon element of the image icon element array comprises at least one of a microstructured void, a column, or a combination thereof integrated into a microstructured layer. Device . 10. The micro-optical security device of claim 10 , wherein the control material is placed in or on at least a portion of the microstructured void, the column, or a combination thereof . The focusing element of the focusing element array comprises at least one of aspherical or aspherical lenses arranged in a hexagonal pattern, or the focusing element of the focusing element array is less than three. From a group containing focusing elements having an f-value and a diameter less than 50 μm, or the focusing element array comprising a wrenchular lens, a cross-hatched wrenchular lens, an aspherical lens, a micromirror, or any combination thereof. The micro-optical security device of claim 1 of choice . The micro-optical security device of claim 1, wherein at least one of the target images or reward images is a floating image, a deep image, or an image capable of transitioning from a floating image to a deep image . The method for manufacturing the micro-optical security device according to claim 1.
When at least part of the image icon element array is viewed through at least part of the focusing element array, the focusing element is integrated with the control pattern element array so that at least one composite image is projected by the image projection system. Including providing the image projection system having the image icon element array layered with the array.
The micro-optical security device provides at least two target images that are spatially tuned so that in a given aligned phase, the in-phase portion of the control pattern element array is focused and at least one reward image is expressed. The above method .
