中文摘要	为了实现大口径、宽视场光学遥感器的辐射定标,研制了新型的直径3 m、出光口直径1 m的可变光谱积分球光源。采用多种波长的发光二极管密集阵列发光单元, 结合卤钨灯发光单元,在400~2500 nm波段实现了绝对辐亮度和光谱分布的动态可调, 开发了光谱自动匹配算法,能够模拟阳光、海水、植被、沙漠等典型目标光谱。参考光源采用循环水冷温控和高精度可编程直流电源驱动技术,保障了光源的稳定性。检测结果表明:光源角度均匀性在60°以内优于99.4%,面均匀性优于99.5%,2 h内稳定性优于99.8%。
英文摘要	To meet the radiometric calibration requirements of optical remote sensor with large aperture and wide viewing field, a spectrally tunable reference light source with 3-m diameter integrating sphere and 1-m diameter exit port is designed. By incorporating multi-wavelength light-emitting diode (LED) modules and tungsten-halogen lamps modules, both absolute radiance and spectral distribution of the light source can be adjustable within 400~2500 nm. A spectral auto-match algorithm is developed to generate solar, ocean, vegetation, desert and other typical target spectrum. LED modules are cooled by water circulating system with high temperature stability and driven by high precision programmable direct current power supplies, which ensures the stability of exit radiation. The test results show that the planar uniformity of the source is better than 99.5% at the exit port, the angular uniformity is better than 99.4% within 60° to the exit normal, and the stability of source is better than 99.8% within 2 hours.
