Abstract

The results of research on the development and application of optical elements placed in the upper part of the window in order to redirect sunlight to the ceiling and into the interior of the room have been summarized and analyzed. There has been a steady trend of transferring such devices to the micro level. The article has described the structures and optical characteristics of three types of the optical microstructures embedded in double-glazed windows: microprismatic films, panels with prismatic microstructures on two sides, and films with embedded micro-mirrors. It has been noted that the use of curved surfaces instead of flat ones in microstructures improves the optical properties and increases the uniformity of the redirected sunlight flux. The designs and properties of optical microelectromechanical systems: switchable micro-mirrors and micro-blinds that were manufactured using microelectronics technology, have been generalized.

车窗光学微结构（综述）

摘要

总结并分析了为了将太阳光重新定向到天花板和房间内部而放置在窗户上部的光学元件的开发和应用的研究结果。将此类设备转移到微级的趋势一直稳定。文章描述了嵌入双层玻璃​​窗中的三种类型的光学微结构的结构和光学特性：微棱柱膜，两侧具有棱柱形微结构的面板以及嵌有微镜的膜。已经注意到，在微结构中使用弯曲表面代替平坦表面改善了光学性能并增加了重新定向的阳光通量的均匀性。光学微机电系统的设计和性能：
