全反射式高分辨率大视场傅立叶变换成像光谱仪的光路结构
摘要：
一种全反射式高分辨率大视场傅立叶变换成像光谱仪的光路结构，整个装置由三反射式前置望远镜、入射狭缝、菲涅尔双面镜、三反射式后置准直镜、三反射式柱面镜、焦平面探测器等部分组成。三反射式前置望远镜将目标成像于一维狭缝上；狭缝的像投射到菲涅尔双面镜上，并被剪切为两束具有一定交角的相干光；这两束光再经过三反射式后置准直镜后成为平行光束并以一定角度投射到三反射式柱面镜；经过聚焦最后投射到焦平面探测器表面，形成一维干涉条纹分布和另一维的灰度图像分布。本发明装置具有高分辨率、宽视场、宽光谱范围、高光通量以及光学结构小型化的特点，特别适合于航空航天遥感对地观测领域的高光谱成像系统。
摘要（英）：

An optical path structure of Fourier transform imaging spectrograph with high resolution and large field in total reflection type is prepared for imaging object on one-dimensional slit by three-reflection mode (TRM) pre-telescope, projecting slit image on Fresenel double-surface mirror and cutting slit image to be two correlation beams with certain cut angle, making two said beam be parallel beam after they are passed through TRM post collimator then projecting it to TRM cylindrical mirror in certain angle, focusing and projecting to surface of focal-plane detector for forming one-dimensional interference fringe and another-dimensional grey image distribution.
