摘要
成像光谱仪在获得景物图像的同时,获得了其连续的光谱特性,具有图谱合一的特点。光谱分光是成像光谱仪关键技术之一。文章讨论了棱镜成像光谱仪的色散特性,以单棱镜为例研究了棱镜色散的非线性缺陷和系统像面弯曲的规律,分析了色散元件前的光学系统成像质量对系统色散的影响。
This paper introduces the dispersion characteristics of the Prism Spectrograph. Take, for example, the single-prism, it discussion the monlinear defect of prism dispersion and the rules of distortion of system image plane. It analyses the influence of the imaging quality of optical system which is mounted before the dispersion components.
