摘要

本文提出了一种由周期性分子排列形成的光栅矢量径向叠加的环形光栅。根据入射偏振态的不同,各向异性光栅产生了环形一阶衍射的偏振依赖关系。为了确定单波长和多波长入射光的偏振状态,我们试图从每个单次衍射图像中提取环状衍射上的光强分布。此外,还提出了一种能够检测光双折射空间调制的系统。最后,我们得出结论,环形衍射的周长光强分布具有充分的潜力。

Polarization information landscapes expanded from single-shot images of ring-like diffraction patterns
In this paper, we propose a ring-type grating in which grating vectors formed by periodic molecular alignments are superimposed radially. Depending on incident polarization states, the anisotropic gratings generate polarization dependencies for the ring-like first order diffraction. To determine the polarization states of incident light for both single and multi-wavelengths, we attempted to extract the optical intensity distribution on the ring-like diffraction from each single-shot diffraction image. In addition, a system that enables the detection of spatial modulation of optical birefringence is proposed. Finally, we concluded that the optical intensity distribution on the circumference of the ring-like diffraction has sufficient potential to be available.
