| 摘 要： | 参考光源是辐射定标系统中的关键设备之一。近年来不同光谱分辨率、不同工作方式光电探测器的发展，需要参考光源在具备稳定性、均匀性等基本特性的同时，能够实现光谱匹配、大动态范围调节和宽波段精细扫描等新的功能。结合以LED为发光单元的可调光谱参考光源和利用宽调谐激光器的单色面光源技术，介绍了新型参考光源的设计、主要性能和部分前期的应用效果。新型参考光源可以与近年发展起来的基于探测器的标准传递技术相结合，在保障和提高绝对定标精度的同时，满足特定的定标技术要求。

| Abstract: | Reference light sources are key devices in a radiometric calibration system. To meet the calibration requirements of recently developed opto-electronic sensors with various spectral resolutions and operation modes, reference light sources are required to possess new functions such as spectral match, large dynamic adjustment range, fine scanning in wide spectrum, as well as the basic features such as high stability and uniformity. This paper gives a brief introduction of the design features, main performances and initial applications of a spectrally adjustable light source based on LED modules and a wide spectrum tunable monochromatic planar light source based on tunable lasers. Incorporated with detector-based transfer standards, these new reference light sources can meet specific calibration requirements and improve absolute calibration accuracy. |
