Abstract
The area array CMOS devices are usually used on the staring imaging space remote sensors on which the wide field angle. Only an RC system cannot match the requirement. So at present, the RC system coupled with a group of relay lens which is always used in the long focal length and wide field angle system can extend the field angle because the aberration of off axis of the RC system can be corrected by the relay lens. In order to reach the high precision alignment of the system, the computer aided alignment technology and the high precision spatial location reconfiguration technology will be introduced. Comparing with the group of relay lens and the secondary mirror both adjusted, this method fixed the group of relay lens. It made the secondary mirror be the only variable. The number of the variable of the alignment was reduced. The efficiency of the alignment was also improved and the period was shortened. The result was that the MTF of all the nine field angles was better than 0.315, which the design result was 0.345. The factor of the alignment was 91 percent.
