Polarization gratings can be realized by polarization holographic recording in photoanisotropic materials. In this paper, we study two types of polarization gratings. One is recorded with two orthogonally circularly (OC) polarized beams and the other one with two orthogonally linearly (OL) polarized beams. The interference of both cases is explored beyond the small recording angle regime. A novel method is proposed to represent the polarization states of the modulation. The diffraction by polarization gratings is studied with rigorous diffraction theory. Simulations based on the Finite Element Method are performed for both OC and OL polarization gratings at small and large recording angles.
偏振光栅可以通过在光各向异性材料中进行偏振全息记录来实现。在本文中，我们研究了两种类型的偏振光栅。一种是用两个正交圆偏振（OC）光束记录的，另一种是用两个正交线偏振（OL）光束记录的。在小记录角范围之外探讨了这两种情况的干涉。提出了一种表示调制偏振态的新方法。利用严格的衍射理论研究了偏振光栅的衍射。基于有限元方法对小记录角和大记录角下的OC和OL偏振光栅进行了模拟。
