由于液晶分子的各向异性，即对不同偏振方向的光折射率不一样，反射光和透射

Since the anisotropic liquid crystal molecules, i.e., the refractive index of light of different polarization directions are not the same, the polarization state of reflected and transmitted light depends largely on the length of the cholesteric liquid crystal pitch, if the wavelength of the incident light and the pitch of the liquid crystal rather, sidebands appear, when the incident light is the same as the helical axis direction of the circularly polarized light

Because the anisotropics of liquid crystal molecules, that is, the refractive index of light in different polarization directions is not the same, the polarization state of reflected light and transmitted light depends to a large extent on the length of the bile phase LIQUID skewed, if the wavelength of the incident light and the liquid crystal pitch is equivalent, the edge band appears, when the incident light is the same as the spiral direction of the axis when the circular polarization light

Due to the anisotropy of liquid crystal molecules, i.e. the refractive index of light in different polarization directions is different, the polarization state of reflected light and transmitted light largely depends on the pitch length of cholesteric liquid crystal. If the wavelength of incident light is the same as the pitch of liquid crystal, the sideband will appear, when the incident light is the circularly polarized light with the same helix direction as the axis<br>
