紫外天体模拟器辐射参数现场校准技术

Calibration device for UV radiation celestial body simulator

紫外天体模拟器为空间探测工程中紫外有效载荷的重要测试和仿真设备。为了解决紫外天体模拟器辐射参数现场校准存在的难题，建立一套便携式紫外天体模拟器辐射参数现场校准装置，实现紫外模拟器瞬态辐射参数校准和高灵敏度辐射参数校准。校准参数包括光谱辐亮度、光谱辐照度等。校准的光谱范围为200~400 nm ，该装置的建立完善国内的紫外校准技术研究体系，填补我国现场计量型的紫外标准的空白。

Importance of ultraviolet calibration is growing fast as ultraviolet payloads are wildly used in national space plan. Calibration device for UV radiation celestial body simulator was established especially for the calibration of instantaneous radiation parameters and high-sensitivity radiation parameters. Parameters such as spectral radiance, spectral irradiance can be calibrated from 200 nm to 400 nm. The calibration device is perspective for its application in national system.
