A holographic liquid crystal polarization grating with a Fabry-Perot structure was developed. Because of its resonant structure, the device offers high levels of control of the diffraction properties of incident-polarized light beams, depending on the resonance conditions. The diffracted light beams are emitted in both the reflection and transmission directions, and the device thus works as a multibranch polarization grating with double optical paths, unlike a conventional polarization grating. These device features were experimentally demonstrated and were also explained theoretically.
研制出了一种具有法布里-珀罗结构的全息液晶偏振光栅。由于其谐振结构，该器件能够根据谐振条件对入射偏振光束的衍射特性进行高度控制。衍射光束在反射和透射方向上均有出射，因此该器件与传统偏振光栅不同，可作为具有双光路的多分支偏振光栅工作。这些器件特性通过实验得到了验证，并从理论上进行了解释。
