B42B 15/00
B42B 15/00
US Classification:
359626, 283 85, 359619
Abstract:
Translucent, transparent, or semi-translucent microlens sheetings with composite images are disclosed, in which a composite image floats above or below the sheeting, or both. The composite image may be two-dimensional or three-dimensional. The sheeting may have at least one layer of material having a surface of microlenses that form one or more images at positions internal to the layer of material, at least one of the images being a partially complete image. Additional layers, such as retroreflective, translucent, transparent, or optical structure layers may also be incorporated into the sheeting.

Assignee:
3M Innovative Properties Company - Saint Paul MN
International Classification:
H01L 21/027
US Classification:
2504921
Abstract:
A method includes scanning a radiation beam with respect to a multi-photon curable photoreactive composition. The radiation beam includes a power sufficient to at least partially cure a volume of the multiphoton curable photoreactive composition. The method further includes modifying a characteristic of the radiation beam as the radiation beam is scanned.

Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
G02B 5/124
US Classification:
359530
Abstract:
Techniques are described for forming microlens sheeting having composite images that appear to float with respect to the plane of the sheeting. As one example, a method comprises forming one or more images within a sheeting having a surface of microlenses, wherein at least one of the images is a partially complete image, and wherein each of the images is associated with a different one of the microlenses, wherein the microlenses have refractive surfaces that transmit light to positions within the sheeting to produce a plurality of composite images from the images formed within the sheeting so that each of the composite images appears to float with respect to the plane of the sheeting, and wherein forming the one or more images comprises forming the one or more images such that each of the composite images is associated with a different viewing angle range.
