摘要
由于红外焦平面器件的像元尺寸和光学系统衍射效应的影响 ,红外成像系统的空间分辨率大大低于可见光成像系统。本文介绍了目前几种主要的提高红外成像空间分辨率的可能方法 :微扫描技术、光瞳滤波器及基于解析延拓理论的超分辨率图像重构技术 ,并对这些方法在工程实际中的应用作了评述。
The spatial resolution of infrared imaging system is frequently lower than that from visible region systems due to diffraction and the finite pixel size of infrared focal plane arrays The Methods of improving spatial resolution of infrared imaging system are summarized, such as microscanning technique, pupil filter and super-resolution image reconstruction on the basis of analytic extrapolation The merit of these methods is also discussed
