摘要
超光谱成像仪是环境减灾-1A卫星搭载的有效载荷之一,采用空间调制傅里叶变换光谱成像(SMFTHSI)原理,针对仪器技术指标、卫星平台以及仪器光学方案等约束条件,文章介绍了超光谱成像仪光机结构设计方法以及设计结果,并采用有限元分析法对设计结果进行了分析计算。
The hyperspectral imager is one of the payloads of the HJ-1A satellite. The principle of Spatial Modulated Fourier Transform HyperSpectral Imaging was adopted in this payload. According to the technical specifications, limitations of the height, the volume on the satellite platform and the optical system layout of the payload, the mechanical structure design was accomplished. In this paper the opto-mechanical design method is introduced and the finite element analysis is used to simulate and validate the design result.
