摘要
近年来,各种微纳光学效应被用于实现结构色甚至更精细的光谱调控,但这类方法大部分都基于彩色滤波原理,其光学效率难以接近甚至超越传统的染料滤波技术。首先介绍高像素密度图像传感器的色彩技术需求,并分析现有商用染料滤波器和微纳光学结构色滤波技术的局限性,然后介绍一类新兴的微纳结构空间分光色彩管理技术,并系统性地分析和讨论其技术原理和发展现状,最后总结该技术面临的挑战和发展趋势。
In recent years,various micro-nano optical effects have been used to realize structural color and precise spectral control,but most of methods based on the micro-nano optical effect are based on the principle of color filtering,and the optical efficiency is lower than that of the traditional dye filtering technology.First,the requirements of color technology of a high pixel density image sensor are introduced,and the limitations of the commercial dye filter and micro-nano optical structural color filter technology are analyzed.Then,a new kind of micro-nano structure spatial spectral color management technology is introduced,and its technical principle and development status are systematically analyzed and discussed.Finally,the challenges and development trend of this technology are summarized.
