| Abstract: | 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. |
