Study on vortex spectra sensing

具有轨道角动量的光涡旋作为光学科学领域的一项最新技术，因其独特的光学特性及其在DNA和生物细胞操作中的应用而受到广泛关注。迄今为止，对光涡旋的产生和小物体的运行进行了大量的研究，但对其传感和测量的研究却很少。在本研究中，首先，我们的目标是生成涡旋光谱。其次，利用具有奇异点的涡旋光谱来揭示生物聚合物的行为和物质组成的相关信息。研究表明，利用制造的轴对称四分之一波片，涡流光谱传感可以检测非均匀物性的极化特性。

Optical vortex having an orbital angular momentum, as a latest technology in the field of optical sciences, has been attracted great interests to its unique optical properties and its applications as operations of DNA and biological cells. Up to day, there are a lot of researches for the generation of optical vortex and the operation of small objects, although there are hardly any researches related on the sensing and/or measurement. In this study, firstly, we aimed at generating the vortex spectra. Secondly, we aimed at bringing out the information related on the behavior of the biological polymer and the composition of the matter using vortex spectra with singularity points. It has been made clear that vortex spectra sensing can detect the properties of polarization of imhomogeneous physical properties using fabricated axisymetrical quarter wave plates.
