摘　　要：论述超大空域凝视热像系统自动设计中的技术难点；运用Ａｉｔｋｉｎ插值方法于自动优化技术排除“溢出”光线；借助人为诱导，充分发挥像差渐晕的作用，改善像面照度的均匀性；给出了Ａｉｔｋｉｎ插值公式、误差分析公式和光阑边缘逼近公式。The technical difficulties in the automadc optindzation of IR fish-eye lenses are overcome and the mid-IR. and far-IR fish-eye lenses were designed. In the automatic optimizations of those lenses the Aitkin interpolation is applied to remove the tmubles caused by total reflection or no intersection of rays. The complex optimization speeds up the optical automatic design, and the artifi- cial expansions of the stop coma and barrel distortion improve the illuminance distribution on the image planes. The artificial expansions of the aberrations are achieved automaticaly by guiding iteration calculation. Facts have proved that the designed IR fish-eye lenses have high qualities.
