中文摘要：
详细论述了液晶透镜的设计理论,并在前人已有的工作基础之上改进制作工艺,得到新型单圆孔电极的液晶透镜。与现在已有的单圆孔电极液晶透镜制作工艺相比,改进体现在：使用光刻和盐酸腐蚀的方法,刻蚀ITO基板得到了具有直径为2mm的圆孔图案的上电极;使用聚酰亚胺取代玻璃作为绝缘层。新型透镜的特性是,工作电压可以低至1.1Vrms,焦距范围为20~480mm,响应时间可达到亚毫秒量级,而在500~1100nm范围内透过率稳定在80%以上。通过实验进一步表明：该液晶透镜的点扩展函数（PSF）与理论值接近,且焦距与工作电压成反比例关系。
英文摘要：
Design theory of liquid crystal was improved based on existing work of other （LC） lenses was described. And its fabrication technology researchers. A new type of LC lens with single circular aperture electrode was obtained. Compared with the existing fabrication technology of the LC lens with single circular aperture electrode, an improved circular electrode of 2 mm diameter on an ITO substrate with an insulation layer of polyimide （PI） instead of glass was etched through photolithography and hydrochloric acid etching. The new type of lenses fabricated by the improved technology has advantages of low work voltage of 1.1 V wide focal length range from 20 mm to 480 ram, short response time of sub-millisecond order, and stable transmittance of higher than 80 percents within the wavelength range from 500 nm to 1 100 nm. Further experiment shows that the point spread function （PSF） of the LC lens approaches its theoretical limit, and its focal length is inverse proportion to its work voltage
