Conventional mos image sensors require polymer onchip microlenses and dyed rgb color filters , which are fragile and extremely susceptible to sunlight exposure and a change in temperature 传统的mos图像传感器需要采用聚合在电路板上的微透镜和染色rgb颜色过滤器,这种脆性材料非常易碎,而且在日晒下和温度变化时极其易受影响。
Two kinds method of design binary subwavelength diffractive microlenses are illustrated with emphasis . i obtained the result that the method of subwavelength pulse - width modulation is better than the method of linear approximation for continuous phase piece in designing binary subwavelength diffractive microlenses by comparing them 重点说明了二台阶亚波长衍射微透镜的两种设计方法,并对两种方法作了比较,得出了亚波长结构的脉冲宽度调制法优于连续位相的线性进似法的结论。
