摘　　要：根据光电成像系统时域和频域特点,在分析调制传递函数的基本理论之后,提出了建立基于MTF的光电成像系统模型,通过分析光电成像系统中的各个环节的传递函数,最终计算得到了系统总的MTF,结合具体的仿真实验,验证了该方法的合理性,可以为光电成像系统设计提供理论依据。According to the characteristics of electro-optical imaging system in time and frequency domain, the model of electro-optical imaging system based on MTF was proposed through analyzing MTF theory. The total MTF of the e- lectro-optical imaging system was calculated through analyzing the MTF of all components, and the simulation was car- ried out. The results verify the correctness of the model, which provides a theoretical foundation for electro-optical ima- ging system design.
