Provided is an anti-counterfeit label with multi-focus multi-layer depth-of-field images. The anti-counterfeit label is sequentially provided with a multi-focus microlens array layer, a transparent base membrane layer and a microtext array layer from top to bottom in a laminating mode, and a metal reflective layer is arranged under the microtext array layer; the multi-focus microlens array layer comprises microlenses which are distributed in an array mode and have multiple focuses; the microtext array layer comprises one set or multiple sets of subunit pattern periodic ordered arrays. The anti-counterfeit label has the advantages that the microtext array layer can be amplified by 80-800 times by the multi-focus microlens array layer. The anti-counterfeit label is particularly suitable for popular anti-counterfeiting and can effectively improve the anti-counterfeit capacity.

An optical product can reproduce a first 3D image of at least part of a first 3D object and a second 3D image of at least part of a second 3D object. The optical product comprises a surface configured, when illuminated, to reproduce by reflected or transmitted light, the first 3D image without reproducing the second 3D image at a first angle of view, and the second 3D image without reproducing the first 3D image at a second angle of view. Each portion of first portions can correspond to a point on a surface of the first 3D object, and comprise first non-holographic features configured to produce at least part of the first 3D image. Each portion of second portions can correspond to a point on a surface of the second 3D object, and comprise second non-holographic features configured to produce at least part of the second 3D image.

A display technique capable of displaying special images. A display includes an image display layer and a mask layer. The image display layer includes one or more colored portions, and displays a transmitted light image corresponding to the one or more colored portions when illuminated with white light. The mask layer includes a transparent material layer having a first major surface and a second major surface, and the first major surface includes one or more regions each composed of first and second strip-shaped parts alternately arranged in a width direction. The second strip-shaped parts are provided with a relief structure. A portion of the mask layer corresponding to at least one of the one or more regions conceals a portion of the transmitted light image corresponding to the second strip-shaped parts.

A micro-optic security device (105) includes a planar array of microlenses (305), which are configured to focus light along a plurality of focal paths (610) associated with a viewing angle. The micro-optic security device further includes an icon layer stack (905) disposed along the plurality of focal paths. The icon layer stack includes a first icon layer (620) with volumes of cured material of a first color (613b) and volumes of substantially transparent material at locations outside of focal paths of the first range of viewing angles. The icon layer stack also includes a second icon layer (640) with volumes of substantially transparent cured material at locations along focal paths of the first range of viewing angles, and volumes of cured material of a second color (637a) at locations along focal paths of a second range of viewing angles.

A moiré image processing device is provided, including a light-transmitting film, a light sensor, and an image processor. The light-transmitting film includes a plurality of microlenses, and a light-incident surface and a light-exit surface, where the microlenses are disposed on the light-incident surface, the light-exit surface, or a combination thereof according to a distribution pattern. The light sensor includes a photosensitive surface, where the photosensitive surface faces the light-exit surface, there are a plurality of pixels on the photosensitive surface, and the pixels sense the microlenses to obtain a photosensitive image corresponding to the distribution pattern. The image processor is coupled to the light sensor, where the image processor performs, according to a virtual image and the photosensitive image, image processing of simulating a moiré effect to generate a moiré image, where the virtual image corresponds to the distribution pattern and is similar to the photosensitive image.
