摘要:
A sheeting includes a layer of a shape-memory polymer material having a surface of microlenses, wherein each of the microlenses is associated with one of a plurality of images within the sheeting. The layer of the shape-memory polymer material is responsive to an external stimulus; e.g., temperature, solvent, or moisture; by transitioning from a first state in which an optical property of the microlenses has a first value to a second state in which the optical property of the microlenses has a second value. The microlenses have refractive surfaces that transmit light to positions within the sheeting to produce a composite image from the images formed within the sheeting when the layer of the shape-memory polymer material is in one of the first state and the second state. At least one of the images is a partially complete image, and each of the images is associated with a different one of the microlenses.
摘要(中):
片材包括具有微透镜表面的形状记忆聚合物材料层,其中每个微透镜与片材内的多个图像中的一个相关联。 形状记忆聚合物材料的层对外部刺激有反应; 例如温度,溶剂或水分; 通过从其中微透镜的光学特性具有第一值的第一状态转换到微透镜的光学特性具有第二值的第二状态。 微透镜具有折射表面,其将光透射到片材内的位置,以在形状记忆聚合物材料层处于第一状态和第二状态之一时从形成在片材内的图像产生合成图像。 图像中的至少一个是部分完整的图像,并且每个图像与不同的一个微透镜相关联。
