  • Television photograph with a wide view-field and high angular resolution can be obtained by the method of image mosaic. A monocentric ball lens make infinity object to image on the spherical surface, of which the centre of circle is at centre of the ball lens. After that every relay lens in a relay lens arrays make respective section imaging on the surface of CCD. Finally we apply image processing technology to put many images together. The design results show that a relay lens array can be made up of 2020 relay lenses view field of 120104.8, F=457.9, F/8, 8.5-billions pixels and angular resolution of 8. With three of this kind of system, we can also achieve 360 panoramic photograph. This new technology in television photography will be used widely in military reconnoiter, airport security monitor, air and ground early warning and sports coverage, etc.
