机载成象光谱仪的光学设计

OPTICAL DESIGN OF THE AIRBORNE IMAGE SPECTROMETER

描述了模块式机载成象光谱仪的光学系统及其主光路、分光组件和会聚单元的设计,分析了基本光学参数之间的制约关系,讨论了衍射光栅、扩展光谱覆盖及光谱定标辅助光路等实际问题.

This paper describes the optical system of the module airborne image spectro-meter (MAIS), including the essentials of optical design for primary optics, dispersion as-sembly and converging lens. The restriction among the primary optical parameters is ana-lyzed. Some practical problems such as diffraction grating, expansion of spectral coveringrange and the collimator for spectral calibration are also discussed.
