number can satisfy the requirements that the optical system should have the characteristics of high resolution and light weight. In this paper
we describe a uncoaxial three-mirror system simply and discuss on the rule of variation of laboratory static Modulation Transfer Function(MTF) at Nyquist frequency of the optical system with average wavelength of incident rays. Accordingly
the feasibility of telescope with big
F
number is analyzed. It is shown that the shorter average wavelength of incident rays and the higher MTF are; the better satisfaction ground resolution requires
which will offer the reference to the lightweight space telescope.
