摘要
视场分割方案是实现宽视场高光谱成像的可行途径之一,成像系统除了空间上需要配准外,辐射亮度也需要匹配.本文主要分析宽视场高光谱成像仪的视场拼接技术的辐射匹配原理和匹配要素,简要介绍了实现途径,通过该途径,成功地实现了一种机载高光谱成像仪的视场拼接,给出了该宽视场高光谱成像仪的飞行试验结果,试验显示辐射匹配结果良好,通过光谱曲线的对比,精度在系统误差范围内.
Field-dividing technology is a feasible method to realize wide-view hyperspectral imager. The wide-view hyperspectral imager has to be radiationally matched besides spatial matching between every single view. In this artiele, the ra- diational matching technology and key factors for hyperspectral imager were analysised, and the method to realize the matching successfully was introduced briefly. Some fly experimental results of the realized hyperspeetral imager were showed. The test results show that the radiational maching is well completed and the precision is in the error of the system allowed by comparing the spectral curves.
