| 摘 要： | 设计了一个红外波段消色差共形光学系统.共形整流罩采用流线型几何外表面,能够有效减少空气阻力,提高导弹飞行性能.但是上述表面破坏了球形整流罩的点对称几何特性,使该系统具有大倾斜、大偏心光学特性,引入依赖于目标视场和瞬时视场的动态像差特性.已报道的文献都是针对单色像差校正问题,而对于大目标视场下单色像差与色差校正难点一直没有相关研究报道.基于实际光线追迹结果、通过衍射元件色散特性和构建适当的光学系统结构,克服了导引头内部有限的空间限制,实现了系统消色差设计.最后设计实例结果表明,系统在整个目标视场范围内均得到较好的成像质量. |

| Abstract: | An achromatic conformal optical system working within infrared waveband was designed.Conformal dome adopts streamlined outer surface,which can reduce air drags and enhance flight performance of missile effectively.Because the above surface breaks the point symmetry of spherical dome,the system may introduce dynamical aberrations depending on Regard of View(FOR) and Field of View(FOV),which is characterized by large tilt and large eccentricity.Most of the published papers studied monochromatic aberrations,wh... |
