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. The images can produce one or more optical effects.

Claims (26)

1 . 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,

wherein the plurality of segments comprises sets of segments corresponding to images of the plurality of images such that as the device is tilted, the array of lenses presents the images sequentially as the device is tilted through different viewing angles, and

wherein the images comprise a first group of images presenting a first icon followed by a second group of images presenting a second icon as the device is tilted, the second icon different from the first icon, at least one of the first or second groups of images presenting an optical effect as the device is tilted.

2 . The optical device of claim 1 , wherein the first or second icon appears static as the device is tilted.

3 . The optical device of claim 1 , wherein the first or second icon appears to move, rotate, or change in perspective as the device is tilted.

4 . The optical device of claim 1 , wherein the first or second icon appears to change size, shape, form, or presentation as the device is tilted.

5 . The optical device of claim 1 , wherein the first icon appears static as the device is tilted.

6 . (canceled)

7 . (canceled)

8 . (canceled)

9 . (canceled)

10 . The optical device of claim 1 , wherein the second icon appears static as the device is tilted.

11 .- 20 . (canceled)

21 . The optical device of claim 1 , wherein the second group of images does not include an element in the first group of images.

22 . The optical device of claim 1 , wherein the plurality of segments comprises a tint, dye, ink, or pigment such that the images comprise color.

23 . The optical device of claim 1 , wherein the images are monochromatic.

24 . The optical device of claim 1 , wherein the images are achromatic.

25 . The optical device of claim 1 , wherein the device comprises a kinoform diffuser providing the diffusing features.

26 . The optical device of claim 1 , wherein the array of lenses comprises at least one 1D lens array comprising a series of lenses in one direction.

27 . The optical device of claim 1 , wherein the array of lenses comprises at least one 2D array of lenses comprising a series of lenses in two directions.

28 . The optical device of claim 1 , wherein the array of lenses comprises a first lens array having a first longitudinal axis and a second lens array having a second longitudinal axis, wherein the first and second arrays are arranged such that the first longitudinal axis of the first array is angled from 5 to 90 degrees with respect to the second longitudinal axis of the second array.

29 . The optical device of claim 1 , further comprising a third group of images presenting a third icon following the second icon as the device is tilted.

30 . The optical device of claim 1 , wherein the first or second group of images presents a third icon at the same time as the first or second icon at at least one viewing angle as the device is tilted.
