  • In order to study influence of incident light on electro-optic characteristics of liquid crystal, the optical properties of liquid crystal were analyzed theoretically based on Jones matrix. By using semiconductor laser with different wavelengths as incident light, electro optical characteristics of liquid crystal were studied experimentally. The results show that the transmission intensity of the liquid crystal sample descends steeply at 4.8V and the threshold voltage of liquid crystal is independent on the wavelength of light source. The oscillograph images show that the incident light affects the response time obviously. The diffraction facula of liquid crystal sample arranges in a ring first and gradually in a line with the increase of voltage. At the same time, diffraction spot is not completely symmetrical. The spatial and energy distributions of the diffraction spot are determined by incident wavelength and power supply voltage. The study is meaningful for the research and development of liquid crystal devices.
