摘要

The performance evaluation model (MRCeye model) of CCD low light level imaging system is deduced on the basis of human eye models and experimental data. It is involved signal to noise in time frequency and modulation transfer function in spatial frequency. It is showed by calculation that the minimum value of MRC is obtained when spatial frequency equals to f_0 c / mrad, MRC increase with the decrease of spatial frequency when spatial frequency f is less than f_0 c / mrad, MRC increase with the increase of spatial frequency when spatial frequency f is larger than f_0 c / mrad, namely, The MRC has band-pass characteristic that is according to the characteristic of human eye.
