Description

一种虚拟影像显示*** 技术领域
本发明涉及一种虚拟影像显示***。

传统投影是将影像直接成像在一个不透明或者透明的屏幕平面上，是2D平面影像，没有立体或全息观赏效果。虽然已有部分用于大型舞台的投影反射型幻影成像***，如专利CN 1294517 C、CN1166210A、CN1035777A，其所使用的用于反射投影***的影像光的反射屏幕，均无制备有特别对应于影像源三色特定波长发光的具有波长选择性反射特性的光学膜层，因此观察者看到的通过反射成像的影像质量较差(亮度与对比度低，色彩饱和度低)，无法获得逼真、清晰、色彩艳丽、高对比度、高影像亮度的、从而具有高拟真度的彩色影像，从而难以欣赏到逼真的立体和全息感受的影像显示。
现有技术通常使用的是具有宽谱反射特性的反射膜系，其光反射针对的是一个从包括大部分可见光范围内(420nm到750nm)的、具有较广连续波长范围的光波全部予以反射，这样会导致无分别地将环境光与影像光全部予以反射，会因环境光的大量掺入而造成影像光本身最终成像显示品质的劣化，难以让观看者看到清晰的、高对比度的、具有真实感以及融入环境感的拟真化全息立体影像。
