    • Hybrid white-light viewable holograms and methods for making them. The holograms are hybrid reflection holograms made using the diffractive structures or gratings of a holographic object such as a transmission hologram or holographic optical element (HOE). The wavefronts of the diffractive structures are converted into a reflection hologram by scanning them with a coherent light source having a profiled narrow beam. The hybrid reflection hologram can exhibit display parameters including the multiple colors, solidity, and color stability of white light reflection holograms, the diffractive color shifting of a white light transmission hologram, three dimensional imaging and a wide variety of dynamic changes. Different areas or images with each of these effects can be combined in a single hologram. These hybrid reflection holograms are ideal for security and forgery prevention applications.
    • 混合白光可见全息图及其制作方法。 全息图是使用诸如透射全息图或全息光学元件(HOE)的全息物体的衍射结构或光栅制成的混合反射全息图。 通过用具有异型窄光束的相干光源对它们进行扫描,将衍射结构的波前转换为反射全息图。 混合反射全息图可以显示包括白光反射全息图的多种颜色,坚固性和颜色稳定性,白光透射全息图的衍射色移,三维成像和各种动态变化的显示参数。 具有这些效果的不同区域或图像可以组合在单个全息图中。 这些混合反射全息图是安全和防伪应用的理想选择。
