天宫一号超光谱仪红外谱段的实验室定标
中国科学院 上海技术物理研究所, 上海 200083
摘要:

天宫一号超光谱仪红外谱段光谱范围是8.0—10.5 μm,采用红外线列焦平面推扫方式成像.通过实验室定标实验,获得了每个探测元对应的辐射响应系数和响应线性度,并得到每一探测元的动态范围与噪声等效温差,验证了图像输出校正效果,同时,根据定标实验误差来源分析计算了最终的辐射定标误差.

Calibration for the thermal band of hyperspectral imager in Tiangong-1
Abstract:

The Tiangong-1 hyperspectral imager has a thermal band with wavelength between 8.0 μm and 10.5 μm, it adopts linear array detectors and broom-push method to obtain image. In this paper, results from laboratory radiation calibration are presented. There included image adjust effects, response parameters and linearity of per detector. According to response parameters, effective quantization code and noise code, temperature range of target which can be detected and noise equivalent temperature D-value were obtained. After analyses about propagation of error, the final calibration error was calculated.
