In order to make sure it will get sub-arcsecond angular resolution in the mission we have to test its resolution performance on ground. The EUT is aligned by Zygo interferometer first and a global wavefront error of 0.152 peak to valley is obtained ( = 632.8nm ). Because of the difficulty of angular resolution test for EUT at its operating wavelengths  we test its optical performance at visible and UV band. The method is to place the resolution test-target on the focal plane of collimator and illuminate the target by visible and UV light espectively  then the collimated light will go through EUT and image at focal plane on CCD. By analysis of the images obtained in experiments we conclude that the angular resolution of EUT is 1.22 at visible light ( = 570nm ) which is very close to diffraction limit (1.20) and according to these results we estimate that the operational wavelength resolution is better than 0.32  meets design requirements. While for UV light  the angular resolution is 1.53 that is different from diffraction limit (0.53)  the error comes mainly from large pixel of EUV camera. 2009 SPIE.   Monte Carlo simulation of light propagation in human tissue models (EI CONFERENCE) 会议论文 3rd International Conference on Bioinformatics and Biomedical Engineering, iCBBE 2009, June 11, 2009 - June 13, 2009, Beijing, China Wang Z.; Wang L.; Zhang Y.

The human brain model and the skin model that were used in our experiments have five layers and seven layers  the separation distance of source and detector should be approximately eight millimeters. Future work was discussed at the end of the paper. 2009 IEEE.  respectively. The backscattered intensity from every layer of the human tissue model was obtained by marking the deepest layer that every photon can reach. The simulation results of brain model indicated that the source-detector separation distance should be selected at three centimeters for studies on the actions of the brain nerve cells   Comparative study of x-ray scattering by first-order perturbation theory and generalized Harvey-Shack theory 会议论文 2009 Wang Y.
