In order to ensure the surface figure of the pointing mirror (460mm long  290mm wide) in spaceborne remote sensing camera  Silicon Carbide was selected as the mirror material. The form of composite triangular and rectangular and the combination of open and closed back was explored in the lightweight design. A new kinematic mount and flexible structure in axis is used to hold the mirror around the lateral surface. The structure can minimize distortions induced by coefficient of thermal expansion mismatch among the materials. This eliminates the bending of the integral mount under the weight of the mirror. Optical performance of the mirror was analyzed under gravity load and temperature load using finite element method. Predicted surface figure error based on the removal of bias  tilt and power was calculated using an in-house Matlab script for mirrors. The pointing mirror assembly was tested using open loop servo control. And the surface figure was checked using interferometer. Surface figure accuracy is better than 1/30 ( 632.8nm  rms). The results show that the kinematic mount induces minimal figure error on the optical surface. 2011 IEEE.

In order to design and manufacture more excellent airborne photoelectric stable turret  modulus of elasticity of 213 GPa and thermal expansion coefficient of 7.9106/K. The frame has decreased the maximum deformation by by 60% and increased the fundamental frequency by 65% as compared with those of aluminum alloy materials  a new type of aeronautical material-particulate reinforced aluminum matrix composite (SiC/Al composite) is investigated. Several crucial technologies  respectively as shown by finite element analysis results. Those are confirmed by vibration test furthermore. Therefore  such as pressureless infiltration technology  a significant lightening effect is achieved and the thermal control load is also reduced. The test result indicates that the stable accuracy of the system achieves 19.8rad and the optical-axis parallelism of pay load is 0.1mrad. The research applies the SiC/Al composites to airborne photoelectric platforms  interface reaction controls and plate's welding are systematically studied. Then  which makes a effective exploration for the new aeronautical material's application. 2011 IEEE.  using SiC/Al composites  the airborne photoelectric stable turret frame is successfully prepared in density of 2.94 g/ cm3
