摘要	研究了一种在1.0～2.5μm短波红外波段上可用于机载精准农业观测的成像光谱仪光学系统。研究分析了用于精准农业探测所需的成像光谱仪科学性能参数,着重改进了Dyson成像光谱仪系统并获得了完善的消像散条件,使得其各组成部分在沿光轴方向和垂直光轴方向均具备足够的空间,确保了狭缝、探测器和光学镜片的光机结构放置。设计成像光谱仪具备良好光学性能,光学系统F数为1.5,视场28°,狭缝长度25 mm,光谱分辨率12.7 nm,空间分辨率1 mrad,系统像差得到充分校正,公差比较宽松。该系统的研究将为精准农业遥感应用提供一种思路。
其他摘要	An imaging spectrometer in the short infrared waveband of1.0-2.5μm was obtained for the precision agriculture observation by air.The scientific performances parameters of the imaging spectrometer were analyzed for the requests of the precision agriculture.The perfect astigmatism corrected conditions were obtained based on the advanced Dyson imaging spectrometer.The enough axial and lateral spaces among each parts of the system guaranteed the arrangement of mechanisms of the slit,the detector and the optical elements.An imaging spectrometer with high optical performances as F number1.5,the field of view28°,the slit length25mm,the spectral resolution12.7nm and the spatial resolution1mrad was designed.The aberrations were totally corrected and the tolerances of the system were loose.The research will be helpful for application of precision agriculture remote sensing.
