based on the aberration balance of Three-Mirror-Anastigmatic (TMA)
a kind of segmented optical design way is introduced
with long focal length
wide field of view (FOV). Segmented system is completely simulated and analyzed by using the way of Fresnel diffraction integral for the exit pupil wavefront; the initial design is modified result from the error analysis and distribution of non-sequential surface; the high order asphere & bigger aperture system is optimized to balance the aberration and make the system more redundancy. A segmented synthetic aperture optical system is designed
whose primary mirror is segmented
