    • A method of making a substantially panchromatic holographic optic element (HOE) is disclosed, comprising depositing a layer of finely granulated silver halide in emulsion or suspension onto a polymeric, plastics or film layer to a depth of less than lOOμm or preferably lOOμm and then exposing to laser light of at least 3 different wavelengths in the visible light spectrum either consecutively or simultaneously and then curing the resulting holographic image recorded in said silver halide layer. The invention also covers a display screen capable of receiving an image signal and interpreting said signal to display said image represented thereby on an image projecting surface of said display screen, said display screen (2) comprising an electronically controlled light transmissive panel (4) , the electronic control of which results in differential illumination of portions of said panel, and at least one reflector (6) disposed adjacent and behind said panel such that light impinging on the surface of said panel can pass through the panel and be reflected to a certain extent by said reflector which is made by the aforementioned method. This renders said substrate and said panel together substantially panchromatically holographically reflective to visible light giving rise to exception brilliance under normal ambient and/or day light.
    • 公开了一种制造基本全色全息光学元件(HOE)的方法,包括将乳液或悬浮液中的细颗粒状卤化银层沉积在聚合物,塑料或薄膜层上,深度小于100μm,优选为100μm,然后暴露 在可见光光谱中连续或同时至少3种不同波长的激光,然后固化记录在所述卤化银层中的所得到的全息图像。 本发明还包括能够接收图像信号并且解释所述信号以在所述显示屏的图像投影表面上显示所示图像的显示屏幕,所述显示屏幕(2)包括电子控制的透光面板(4) 其电子控制导致所述面板的部分的差分照明,以及设置在所述面板之后和之后的至少一个反射器(6),使得入射到所述面板的表面上的光可以穿过面板并被反射到一定的 通过上述方法制成的反射器。 这使得所述基板和所述面板基本上全色地全息地反射到在正常环境和/或日光下产生异常亮度的可见光。
