Description
Summary:碩士 === 國立中山大學 === 物理學系研究所 === 99 === In this research, the polarization converters were manufactured by impinging intensity-gradient-distribution laser on DDLC (dye-doped liquid crystal) samples, which the gradient distributed light intensity was produced by applying linear variable ND filter. The performances of these polarization converters were demonstrated, which can convert a linear polarized incident light into a circular polarized light or an elliptic polarized light. The influence of cell gap and beam size of probe beam on the DDLC polarization converter has been discussed.
