Sheeting with composite image that floats
First Claim
1. A method comprising:
- illuminating a sheeting having a surface of microlenses with a divergent energy beam to form a plurality of images within the sheeting, wherein a center of the energy beam is offset from a surface normal of the sheeting, wherein at least one of the images formed within the sheeting is a partially complete image, and wherein the images are associated with different microlenses of the sheeting,wherein the microlenses have refractive surfaces that transmit light to positions within the sheeting to produce one or more composite images from the images formed within the sheeting that appears to float with respect to the surface of the sheeting.

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.

16. A sheeting comprising:
-
a layer of material having a surface of microlenses that form a plurality of three-dimensional images within the sheeting, wherein at least one of the images formed within the sheeting is a partially complete image, and wherein the images are associated with different microlenses of the sheeting, wherein the microlenses have refractive surfaces that transmit light to positions within the sheeting to produce one or more composite images from the images formed within the sheeting that appears to float with respect to the surface of the sheeting. - View Dependent Claims (17, 18, 19, 20, 21)
