In order to minimize the effect of central obstruction on the image quality of reflecting optical system, the off-axis three-mirror reflective system plays an important role in application and research. The advantage of the off-axis three-mirror reflective optical system is analyzed, the calculation method of the structural parameters of co-axial three-mirror reflective optical system is described. A system with large field-of-view and long focal length is proposed. The results show that the system has good image quality.
