摘　　要：针对温度变化使光电系统成像质量下降的问题,从图像模糊程度的角度,分析了温度变化对系统离焦的影响,建立了离焦模糊图像的数学模型,进而揭示了温度变化对成像模糊的影响规律。利用建立的数学模型,对一幅清晰的图像进行仿真实验,仿真结果表明:温度变化越大,光电系统成像越模糊。通过研究温度变化对光电系统成像模糊的影响,为光电系统的环境适应性设计提供了重要的参考。In view of the problem that temperature variation leads to the degradation of electro-optical system imaging quality, the influence of temperature variation on system defocus was analyzed. Mathematical model of defocused image was established, and then the influence discipline of temperature variation on image blurring was revealed. A clear image was simulated based on the established mathematical model, and the simulation results show that the more the temperature changes, the more blurred electro-optical system imaging becomes. By studying the influence of temperature variation on imaging blurring of electro-optical system, this provides important references for environmental adaptability design of electro-optical system.
