For the Space-borne optical imaging payload system design, light weighting and moderate stiffness of mirror andor mirror fixation device is very important aspects. The front surface of mirror is regulated by optical performance requirement, but the shape of backplate of mirror is to be optimised while satisting the required stiffness and weight. According to the results, the best shape of backplate cell is triangular. And also related geometric dimensions and the optimised mounting point of MFD(Mirror Fixation device)is presented. Finally, matural frequencies and mode shapes of mirror stucture are analysed.
