亚像元成像技术是实现相机小型化、提高相机空间分辨率的有效方法。文章介绍了国内外主流的亚像元成像技术,分析了采样方式对标称分辨率及有效分辨率的影响。提出了基于倒易晶胞理论的自适应倒易晶胞用于调整错位频谱的方法,进一步提高了遥感器的有效分辨率。%Subpixel imaging technology is a state-of-the-art method to reduce the size of camera and improve the spatial resolution.This paper introduced the main subpixel imaging systems and discusses the resolution under different sampling systems.On the basis of reciprocal cell,adapted reciprocal cell was used to correct the vicarious spectrum and improve the effective resolution still further.
