研究了正模式聚合物稳定的胆甾相液晶（ Ｐ Ｓ Ｃ Ｔ）光阀开、关态时的光透过率在 ４００～１６００ｎｍ 波段的分布特性，通过实验分析了聚合物浓度和胆甾液晶的螺距对光阀在关态时光透过率随波长分布特性的影响。优化制作条件，制作出一种新型的 Ｐ Ｓ Ｃ Ｔ 光阀，配合 Ｃ Ｃ Ｄ 摄像器和计算机，设计发明了一种火灾监控装置，通过对高温物体辐射出的近红外光的监测，可以准确报警。
The positive mode polymer stabilized cholesteric liquid crystal (P S C T) light valve was used to analyze the distribution of light transmittance in the 400-1600 nm wavelength range. The effects of polymer concentration and cholesteric liquid crystal Of the pitch on the light valve in the closed state when the light transmittance with the wavelength distribution characteristics. Optimized production conditions to produce a new type of P S C T light valve, with C C D camera and computer, the design invented a fire monitoring device, through the high temperature objects emitted by the near-infrared light monitoring can be accurate Call the police.
