Abstract: A document, product, or package, such as a banknote, passport or the like comprises structures having dichroic effects that change color with viewing angle in both transmission and reflection. Such structures can be useful as security features that counter the ability to effectively use counterfeit documents, products, packages, etc.

Abstract: A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

Abstract: An optical device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. In some examples, individual ones of the first and second segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the first and second segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.

Abstract: An optical product can be configured, when illuminated, to reproduce an image that appears to be a 3D image of at least a part of a 3D object. The optical product can include a surface comprising a plurality of portions. Each portion can correspond to a point on a surface of the 3D object. One or more non-holographic features can be disposed within each portion configured to produce at least part of the image without relying on diffraction. An interference optical structure can be disposed on one or more features. A gradient in the features can correlate to a surface normal of the surface of the 3D object at the corresponding point. An orientation of the features can correlate to an orientation of the surface of the 3D object at the corresponding point.

Abstract: An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.

Abstract: An optical product includes an array of lenses and first and second plurality of portions disposed under the array of lenses. Individual ones of the first plurality of portions can correspond to a point on a surface of a first 3D object, and include first non-holographic features configured to produce at least part of a first 3D image of the first 3D object. Individual ones of the second plurality of portions can correspond to a point on a surface of a second 3D object, and include second non-holographic features configured to produce at least part of a second 3D image of the second 3D object. The optical product can include an interference optical structure disposed with respect to the first and/or second non-holographic features.
