我們提出以角度多工搭配極化多工在複合多工的全像記憶體中做正交極化資料的同時讀取架構。在十個不同儲存角度的極化多工下，使用複合多工的儲存方式儲存二十張全像影像在鈮酸鋰晶體。在每一個角度下的全像儲存中，我們藉著使用極化多工的方法將兩張正交極化的影像多工儲存在鈮酸鋰晶體相同的角度位置。兩張正交極化的影像不僅可以被線性極化的讀取光做同時的重建也可以用極化分光鏡做分離並且可以獨立看到每張重建的影像。我們藉由分析等效電光係數來決定一個適當儲存角度的多工儲存架構。我們也在這種儲存架構下推導出儲存每張影像所需的曝光時間。

Orthogonal polarization simultaneous readout technique in a hybrid-multiplexed memory using angular multiplexing and the polarization multiplexing is presented. 20 holograms were hybrid-multiplexed in a single LiNbO3 crystal with 10 angular positions for angular multiplexing. In each angular position of the holographic memory, two images with orthogonal polarization are multiplexed in the same spatial location inside the LiNbO3 via polarization multiplexing. These two orthogonally polarized images can be reconstructed simultaneously with a linear polarization reading beam but they can be separated with a polarization beam splitter, and accordingly each of them can be viewed independently. A suitable recording angle for this multiplexing technique is determined by analyzing the effective electro-optic coefficient. The exposure schedule for this method is also derived.
