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.
Claims31
An optical device comprising:
- an array of lenses;
- and
- a plurality of segments disposed under the array of lenses, the plurality of segments corresponding to a plurality of images, the images comprising at least one icon and at least one background,
- wherein the plurality of segments comprises smooth features and diffusing features, the smooth features defining one of the at least one icon and the at least one background, the diffusing features defining the at least one background when the smooth features define the at least one icon, and the diffusing features defining the at least one icon when the smooth features define the at least one background, and
- wherein the plurality of segments comprises ten sets of segments corresponding to ten images of the plurality of images such that as the device is tilted, the array of lenses presents the ten images sequentially as the device is tilted through 10 different viewing angles.
