摘要
提出了一种有效的特殊整流罩及其像差校正器的设计方法，运用Wassermann-Wolf微分方程组（W-W方程组）的原理，通过在商业光学设计软件中编译宏程序曲面拟合的方法得到校正器最佳面形，从而可以校正整流罩引入的球差、彗差，使系统成像质量得到较大的改善．文章在基于W-W方程的基础上，针对应用于红外系统的特殊整流罩做了实际方案设计，研究的光学系统工作谱段为中波红外，视场大干3．5度，F数F／1-F／2．5，系统采用了复杂化的R—C系统，最终成像质量达到衍射极限，可以满足特殊条件下的红外谱段成像要求，具有较高的实用价值．
An efficient approach of designing a special dome and its aberration corrector was presented. By using the method of Wassermann-Wolf differential equations, the optimum contour of the corrector was obtained through a macro program in commercial optical design software. This corrector reduces spherical aberration and coma which are introduced by the dome, thus it improves the imaging quality of the system. Actual program design of a special dome applying to infrared system was made based on the Wassermann-Wolf algorithm. It works in the spectrum of middle infrared with a field of view more than 3.5° and an F number of 1 -2.5. A complex R-C form was adopted to make the final imaging quality meet the diffraction limit. The whole system satisfies the imaging requirements in the infrared wave band, and it has a high practical value.
