High Definition x-rays-visible Image LccLV Projectors

本文介绍了高清晰度x射线—可见图像LccLV(液晶复合材料光阀)投影仪,该投影仪由图像输入和投影系统组成。讨论了对比度与条纹光学投影系统光效间的关系,并研究了Lcc器件的散射特征。全彩色投影仪的对比度为80:1,亮度大于1800流明(ANSI)。

This paper introduces a high definition x-rays-visible image LccLV projector whichconsists of the input image system image system includes a transparent substrate, an electro luminescent layer, a reflective layer, an opaque layer, a photoconductive layer, x-rays permeable electrode, and a covering layer. This input image system converts an input image x-rays image to a visible image with satisfactory brightness. The projection system includes optical addressed LccLV and a schlieren optics. The relationship between the contrast ratio and the optical efficiency of a schlieren projection system is discussed. The scattering characteristics of a reflection Lcc cell is evaluated. The projector displays the full-color pictures with a contrast ratio of 80:1 and a brightness greater than 1800 ANSI lumens.
