Faithful Reconstruction Condition of Linear Polarization Holography
摘要
在基于张量的偏光全息理论的基础上,使用偏振方向在入射面内的线偏振光作为记录参考光,记录干涉夹角为90°时,只需满足再现光与记录参考光的偏振方向非相互正交,就可以实现对信号光偏振态的忠实再现,再现光光强受读取参考光偏振态的影响。理论与实验结果证实了这一更宽松条件下对信号光忠实再现的可能性。该结论有助于拓展人们对偏光全息理论的认知,并可依此结论设计和制作出用于改变入射光传播方向的偏振器件。
Abstract
According to the tensor based polarization light holography theory, we find that the faithful reconstruction of the polarization state of the signal light can be realized as long as the polarization directions of the read reference light and the reconstructed light are not orthogonal to each other, when the linearly polarized light with polarization direction in the incident plane is taken as the recording reference light and the interference angle at the recording stage is 90°. Besides, the intensity of the reconstructed light is affected by the polarization state of the read reference light. Furthermore, the faithful reconstruction of signal light under more relaxed conditions is verified by the theoretical and experimental results. This conclusion is helpful to extend our cognition of polarization holography, and based on this, we can design and fabricate polarization devices to change the propagation direction of the incident light.
