The dimension and configuration of space camera is mainly dependent by the optical system of the camera. It is useful for the space camera get small

light weight and stabilization that to study several optical system configurations for one application purpose. This paper describes high resolving visible space camera which takes sun synchronization orbit and TDI CCD push-bloom imaging method. Assume the orbit height is 500 km

the grand sample distance is 0.5 m. Analyzed six kinds optical system configurations using the CODE V optical design software

the obtained results have different F number and FOVs(field of view) of each others

and presents useful optical design data. In the practical applications

according to the ground swath width determine the FOV

then choice the optical system configuration which can satisfy the needed FOV and small dimension.
