摘要
介绍了宽视场长波红外(LWIR)光学系统技术指标。离轴三反射镜消像散(TMA)型光学系统光谱覆盖范围宽,可提供一个空间分辨率高、观测范围大的无遮挡视场,能够在 F 数相对较小的光学系统中实现接近衍射极限的光学性能。TMA 型光学系统能满足推扫式 LWIR 扫描仪所要求光学系统大观测视场、高光学效率等指标,可作为预先研究星载遥感仪的光学结构。
A wide-angle optical system for the LWIR push-broom scanner is described in this paper. The off-axial three-mirror anastigmat(TMA) can provide a wide field of view(FOV) with high spatial resolution, it operates at fast F numbers and exhibits near-diffraction-limited performance in the LWIR wavelength region, so it can be used on the spaceborne remote sensor in the future.
