| 摘 要： | 根据人眼视觉实验，对光电成像系统的性能评价方法进行了理论研究，分析了视场角ω，成像系统性能σs，以及角放大率Γ对光电成像系统与人眼存在的最佳匹配的影响，初步实现了定量描述电视型成像系统的最佳观察距离和直视型最佳目镜焦距的客观现象，所得结果与实际基本一致。

| Abstract: | Performance evaluation of electro-optical imaging system is investigated on the basis of human visual experiments. The effects of viewing angle ω,quality factor σ-s and angle magnification Γ on the optimal matching of electro-optical imaging system and human eyes are discussed. It's explained roughly that there is a optimum viewing distance for TV imaging system and a optimum focal length for viewing directly imaging system. The result is consistent with actual basically. |
