Abstract: A liquid crystal optical device has a layered structure with split liquid crystal layers having alignment surfaces that define in a liquid crystal material pre-tilt angles of opposite signs. Four liquid crystal layers can provide two directions of linear polarization. In the case of a lens, the device can be a gradient index lens, and the alignment surfaces can have a spatially uniform pre-tilt.

Abstract translation: 液晶光学器件具有层状结构，其具有分离的液晶层，其具有以液晶材料限定相反符号的预倾角的对准表面。 四个液晶层可以提供两个线性极化方向。 在透镜的情况下，该装置可以是梯度折射率透镜，并且对准表面可以具有空间上均匀的预倾角。
