【Abstract】 The paper presented the working principle and design requirements of an optically addressed liquid crystal light valve(LCLV) which was based on the ultraviolet light sensitive materials BSO crystal.Photoconductive properties of BSO were studied.The mechanism of BSO crystals’ photoconductivity effect was discussed.The test method of the BSO crystals’ photoconductive effect was design.The photoconductive properties of BSO crystals were measured.The measurement result indicated that the BSO crystals have the good photoconductive properties under ultraviolet light and the BSO crystals can be used as the photosensitive layer of the optically addressed LCLV.The impedance characteristics of liquid crystal are measured and concluded.Finally,BSO LCLV was fabricated.The results showed the light valve worked.更多还原
