| 摘 要： | 本文报道用聚乙烯咔唑-2,4,7三硝基芴酮电荷转移复合物作光导层,与向列型及胆甾向列型混合液晶组成的夹心池结构制成的扭曲场效应、相变存储效应及动态存储效应三种直流透射式光阀及其性能的研究结果。制得的光阀均有明显开关效应。此外,还详细研究了扭曲场效应液晶光阀的阈值电压、对比度及上升时间与写入光功率的依赖关系。用白光写入,He-Ne激光读出,在扭曲场效应光阀上可实现非相干光-相干光转换,得到图象。用MTF法测得的光阀分辨率为34lps/mm。

| Abstract: | In this paper the d.c. transmission mode liquid crystal light valves (LCLVs) made from thin films of polyvinylcarbazole (PVK) and trinitrofluorenone (TNF) charge transfer complex coupled with nematic liquid crystal or cholesteric-nematic liquid crystal are reported. Results of the studies on the LCLVs made from sandwich structure consisting of thin films of PVK-TNF and three different kinds of liquid crystals, including twisted nematic field effect, phase transition storage effect and dynamic storage effect liquid crystals, are described. Switching effects of these LCLVs have been observed. In addition, the threshold voltage, contrast ratio and rise time of the twisted nematic LCLVs as a function of input light intensities have been studied. Projected image from the twisted nematic LCLV (incoherent-to-coherent conversion) has been obtained. The resolution of the light valve determined by MTF method is approximately 34 lps/mm. |
