摘要： An apparatus and method wherein polarization rotation in alkali vapors or other mediums is used for all-optical switching and digital logic and where the rate of operation is proportional to the amplitude of the pump field. High rates of speed are accomplished by Rabi flopping of the atomic states using a continuously operating monochromatic atomic beam as the pump.

摘要： A passive backlight film stack can be composed of several light shaping diffusers, which do not use brightness-enhancing films, light pipes or directional turning films. The passive diffuser stack can be used with direct-view backlights or with the diffuser films, each from 100 to 300 micrometers thick, stacked on top of one another. The passive stack assembly can be formed by two elliptical diffuser films (having different light distribution profiles in horizontal and vertical planes) and one circular diffuser film (with homogeneous distribution in both planes). Each film within the stack has a micro-relief surface diffuser pattern ranging from 5 to 200 microns on a rigid substrate achieved by means of single beam recording in photosensitive media. The light shaping diffusers in the proposed stack have special physical and geometrical characteristics.
摘要翻译： 无源背光膜堆叠可以由几个不使用亮度增强膜，光管或定向转向膜的光成形漫射器组成。 无源漫射器堆叠可以与直视背光灯一起使用，或者每个厚度为100至300微米的漫射膜彼此堆叠。 无源堆叠组件可以由两个椭圆形漫射膜（在水平和垂直平面中具有不同的光分布分布）和一个圆形漫射膜（在两个平面中具有均匀分布）形成。 堆叠中的每个膜具有在通过光敏介质中的单光束记录实现的刚性基板上的5至200微米范围内的微浮雕表面漫射器图案。 所提出的堆叠中的光成形漫射器具有特殊的物理和几何特征。
