本文针对液晶透镜在变焦眼镜方面的应用,研制完成了具有取向转换膜的偏振无关的模式控制液晶透镜。首先通过仿真,论证了采用取向转换膜实现偏振无关的模式控制液晶透镜的可行性,接着在实验中研究并优化了取向转换膜的制备参数,最后完成了偏振无关的液晶透镜的制备。测试结果表明,8 mm孔径大小的液晶透镜具有偏振无关的特性,同时具有变焦调节特性,实现了0~1.590 D的屈光度调节。
Aiming at the prospect of applying liquid crystal (LC) lens to zoom glasses, an electrically tunable-focusing and polarizer-free LC lens with an alignment conversion layer is developed. Through simulation, the feasibility analysis of double-layer modal LC lens was conducted. After optimizing the synthesis parameters of alignment conversion film, a polarizer-free LC lens sample was prepared. The imaging and optical interference of LC lens was studied to discuss the polarization independence and image quality. The test results show that the 8 mm aperture LC lens realizes polarization independence and possesses diopter adjustment from 0 D to 1.590 D.
