可变光学延迟器
摘要：
本发明公开了一种次波长光栅，其被放置在液晶可变光学延迟器的内部以降低可变光学延迟器产生的光学延迟的偏振相关性。相对于传统的波片，小厚度的次波长光栅降低了由于次波长光栅的单元内放置所带来的驱动电压的不利后果。
摘要（英）：

A sub-wavelength grating is placed inside a liquid crystal variable optical retarder to reduce polarization dependence of the optical retardation generated by the variable optical retarder. A small thickness of the sub-wavelength grating, as compared to a conventional waveplate, reduces the driving voltage penalty due to the in-cell placement of the sub-wavelength grating.
