红外高光谱基准载荷样机测试数据（2024年）

采用傅里叶红外光谱探测技术，开展红外高光谱基准载荷技术研究，研制具有量值可溯源、光谱连续、光谱分辨率高等特点的红外高光谱载荷样机，作为红外基准载荷核心载体，将为我国未来在长波红外成像、高光谱探测、高精度探测等目标奠定扎实的技术基础，为提高我国红外遥感载荷定量化水平发挥重要作用。
2023年4月和2024年4月，在中国科学院上海技术物理研究所环模实验室，获得了红外高光谱基准载荷样机的视场测试和辐射定标数据，并计算了瞬时视场、光谱覆盖范围、灵敏度和定标不确定度。

Adopting Fourier transform infrared spectroscopy detection technology, this study carried out research on infrared hyperspectral reference payload technology, and developed an infrared hyperspectral payload prototype featuring traceable metrological values, continuous spectrum, and high spectral resolution. As the core carrier of infrared reference payloads, it will lay a solid technical foundation for China's future goals including long-wave infrared imaging, hyperspectral detection and high-precision detection, and play a critical role in improving the quantitative level of China's infrared remote sensing payloads. In April 2023 and April 2024, the field-of-view test and radiometric calibration data of the aforementioned infrared hyperspectral reference payload prototype were acquired at the Environmental Simulation Laboratory of the Shanghai Institute of Technical Physics, Chinese Academy of Sciences. Subsequently, the instantaneous field of view (IFOV), spectral coverage, sensitivity, and calibration uncertainty were calculated.
