We propose a polarization superposition orthogonal theory based on tensor polarization holography. Based on this theory, the holographic multiplexing capability can be improved measurably. The orthogonality of polarization waves is characterized by the null reconstruction in polarization holography, achieved through the superposition of multiple basic polarization reference waves. This paper analyzes the orthogonality of linear polarization wave superposition and circular polarization wave superposition using the tensor polarization holography theory. Using the polarized holography multiplexing technique, we experimentally verify the orthogonality of polarization wave superposition. Our experimental results align with the theoretical analysis, indicating potential applications in polarization encoding and decoding by this theory, thereby diversifying optical encryption technology Additionally, we demonstrate that polarization superposition orthogonality holds significant promise for optical control technology.
我们提出了一种基于张量偏振全息术的偏振叠加正交理论。基于该理论，全息复用能力可得到显著提高。偏振波的正交性通过偏振全息术中的零重建来表征，这是通过多个基本偏振参考波的叠加实现的。本文利用张量偏振全息术理论分析了线偏振波叠加和圆偏振波叠加的正交性。利用偏振全息复用技术，我们通过实验验证了偏振波叠加的正交性。我们的实验结果与理论分析一致，表明该理论在偏振编码和解码方面具有潜在应用，从而使光加密技术更加多样化。此外，我们证明了偏振叠加正交性在光控制技术方面具有重大前景。
