摘要	Stability of wavefront aberration (WFA) has great impacts on imaging quality of space camera, which is a major performance index for those. With regard to possible gravity orientation and temperature range of space camera in manufacture and orbit, the mirror's tolerances and profile errors were calculated through FEA, and WFA was calculated by optical software using those. By simulating multi-orientation gravity states and adjusting environment temperature 204 in laboratory, WFA of the space camera was measured and tested, the average result changed from /14.7 to /12.4 at all states, the worst was /11 for single field. The testing data was nearly in accord with the calculate value, the mean range were-0.012 6-0.003 1, the max difference error was-0.023. Moreover, the MTF to was tested validate the system stability, the result achieved 0.21, there were only 4.8% errors at choosing states. The method can be used to inspect and confirm the imaging performance stability, which has been used in mail:jan_zxx@163.com wide-field TMA space camera, guiding design and finding week point, through analysis and testing, the data well illustrated the performance stability at all states.
