| Abstract: | The diffraction phenomena of a kind of liquid crystals were studied.When the incident linear-polarized light had travelled through the special liquid crystal under certain electric field,the diffraction patterns of periodic structures would occur.Based on these experiments,this paper discussed the relation between diffraction patterns and inner structures,and the polarization characteristics of the diffraction patterns. |
