The off-axis three mirror anastigmatic (TMA) system has been proven a sort of excellent optical system for space borne camera especially the compact cameras because of its high modulation transfer function (MTF) and large field of view (FOV).We propose several new methods that can be applied on the space-borne TMA system to improve its performance.Because all the improvement is realized by manipulating the pupil function indirectly,these new methods are jointly called intelligent pupil technology.
