摘要	There are no proper radiation calibration methods and devices for EUV space cameras, so this paper proposes a small target imaging radiation calibration method suitable for the EUV band and establishes a radiation calibration device based on the method in a lab. This method uses a standard transfer detector to calibrate the radiance of the small target. Then, a EUV space camera is used to take the small target's image in its center Field of View (FOV) and to get its radiance responsivity. Finally, by adjusting the motion platform, the small target's images in different FOVs are taken by the EUV camera, and the radiance responsivity in different FOVs are obtained. The developed radiation calibration device consists of a light source system, standard transfer detectors, a vacuum tank and a four-dimensional motion platform fixed in the camera. The light source system consists of a hollow cathode light source, an extreme ultraviolet grazing incidence monochromator, and a collimating mirror generating a parallel monochromatic beam. The standard transfer detectors are used to calibrate the beam's photon flux and small target's radiance and the motion platform enables the camera to take the small target's images in different FOVs and to get camera's responsivity in different FOVs. A EUV camera has been calibrated by this device, and the error sources are analyzed. The calibration results indicate that its accuracy is better than 15% and implements the radiation calibration for whole bands. 2016, Science Press. All right reserved.
