| Research Abstract |
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.
