abstract = "Residual figure errors on the polished optical surfaces would affect the quality of the optical system. Among them, mid spatial frequency defects would produce small angle scattering, which has the effects of smearing out of the imaging core and degrading the resolution. In this paper, taking a classical Schmidt-Cassegrain system into consideration and a cosine-modulation function is stacked onto the primary mirror surface to simulate and analyze the effect of the mid spatial frequency. Actually, the mid spatial frequency irregularities could decay the resolution of imaging systems although the conventional specifications such as RMS and PV meet the requirements.",
