摘　　要：紫外像增强器作为导弹紫外告警系统、紫外预警系统以及各类紫外辐射监测系统的核心部件,其参数准确与否,直接影响到系统的图像质量。为保证测试数据的准确性,研制紫外像增强器分辨力校准装置,校准装置所用紫外光源是波长范围为200 nm^400 nm的紫外光,相对应的分辨力靶、滤光处、光学成像系统均要求能够透射紫外光,由于紫外波长较短,容易引起散射效应而产生大量的杂散光,设计的分辨力靶采用紫外级石英,紫外光学成像系统采用透射式结构,选用同轴共轭透镜作为紫外光学成像系统。实验和测量不确定度分析验证校准装置的测量不确定度为5%。The UV(ultraviolet)image intensifier is the core part of the missile UV warning system,UV early warning system and the various UV radiation monitoring systems,and the accuracy of its parameters directly affects the image quality of the system.In order to ensure the accuracy of the test data,an resolution calibration device of the UV image intensifier was developed.The UV light source used in the resolution calibration device of the UV image intensifier was the UV light with a wavelength range of 200 nm to 400 nm.The corresponding resolution targets,filters,and the optical imaging systems were all required the ability to transmit the UV light.Due to the short wavelength of the UV light,it was easy to generate a great deal of stray light caused by the scattering effect.The UV quartz was adopted by the designed resolution target,the transmission structure was adopted by the UV optical imaging system,and the coaxial conjugate lens was selected as the UV optical imaging system.The experiment and the measurement uncertainty analysis verify that the measurement uncertainty of the calibration device is 5%.
