摘　　要：本文讨论了视场等于180度的球幕鱼眼镜头的光学设计问题。介绍了它的应用和成象原理。球幕直径为24米。依据象差渐晕理论,追迹了一系列子午和弧矢光线以及空间光线从而可以绘制点列图。通过实例给出了有关象质信息。The optical design of a semi-spherical screen fish-eye objective with field angle 180 degrees has been studied. Its application and theory of image formation have been introduced. The screen diameter equals 24 meters. Based on the concept of aberrational vignetting, both the meridional and the sagittal light rays as well as the skew rays can be traced so that the calculation of spot diagram has been successfully finished. Firsthand information concerning image quality is shown. Finally a practical example is given.
