Based on the modulation transfer-function model associated with the atmosphere turbulence,the impact on the electro-optic performance of short wave infrared (SWIR) detector,mid wave infrared (MWIR) detector and long wave (LWIR) detector,which induced by modulation transfer-function(MTF) and point spread function(PSF) is studied numerically.It is shown that the intensity of atmosphere turbulence has evidently influenced upon the spatial resolution,the weak turbulence has a greater impact on the electro-optic performance of MWIR detector and LWIR detector,the turbulence-induced MTF is worse than that of the diffractioninduced under condition of weak turbulence,the detector spatial resolution decreases with the aperture diameter and wavelength increasing.
