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200~400nm,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。
The UV celestial simulator is an important test and simulation device for UV payload in space exploration project. In order to solve the problem of on-site calibration of the radiation parameters of ultraviolet celestial simulators, a set of on-site calibrating device for radiation parameters of portable ultraviolet celestial simulators was established to calibrate the radiation parameters of ultraviolet simulator and the calibration of radiation parameters with high sensitivity. Calibration parameters include spectral radiance, spectral irradiance and more. Calibration of the spectral range of 200 ~ 400nm, the device to establish and improve the domestic UV calibration technology research system to fill our field measurement of UV standards blank.
