    • A reflective liquid crystal lightvalve for modulating the polarization of incident light within a specified band of wavelengths into on and off states, comprises: (i) a pixelated reflective backplane; (ii) a first liquid crystal layer, positioned proximate the pixelated reflective backplane, the first liquid crystal layer being tuned in the off state to switch incident light at the center of the specified band of wavelengths into a state that is not fully off; and (iii) a second liquid crystal layer, positioned proximate the first liquid crystal layer wherein the first liquid crystal layer is positioned between the second liquid crystal layer and the pixelated reflective backplane, the second liquid crystal layer having a birefringence which, at a given depth within its thickness, is substantially equal and opposite to a birefringence of a layer within the first liquid crystal layer that is located at a matching distance from a midplane separating the first and second liquid crystal layers.
    • 用于将特定波长波长内的入射光的偏振调制为导通和截止状态的反射型液晶光阀包括:(i)像素反射背板; (ii)位于像素化反射背板附近的第一液晶层,第一液晶层被调谐到关闭状态,以将特定波段波长的中心的入射光切换到未完全关闭的状态; 和(iii)位于第一液晶层附近的第二液晶层,其中第一液晶层位于第二液晶层和像素反射背板之间,第二液晶层具有双折射,在给定的 其厚度之间的深度基本上等于和相对于第一液晶层内的与分离第一和第二液晶层的中平面相匹配的距离处的层的双折射。
