A scattering-free, polarization controllable Fresnel zone plate lens is demonstrated using a photo-induced alignment of the dye-doped liquid crystal film. This photo-aligned liquid crystal zone plate provides orthogonal polarization states for odd and even zones. The different focus orders can be separated because of their different polarization states. The fabrication process is relatively simple and the operation voltage is less than 5 V(rms).
利用染料掺杂液晶薄膜的光致取向，展示了一种无散射、偏振可控的菲涅耳波带片透镜。这种光取向液晶波带片为奇数区和偶数区提供正交偏振态。由于不同聚焦级具有不同的偏振态，因此可以将它们分开。制造工艺相对简单，工作电压小于5V（均方根值）。
