摘要
为了校正大长径比、大扫描视角共形整流罩引入的动态像差,提出了一种固定自由曲面透镜阵列校正器。通过设计透镜阵列校正器中各透镜自由曲面的面形和旋转角度,校正不同扫描视角大长径比共形整流罩引入的动态像差。实验结果表明,自由曲面透镜阵列校正器可以对长径比为1.2的共形整流罩实现±50°扫描视角的动态像差校正。这种新型校正器具有动态校正器和固定校正器的优点,可适用于扫描视角大、长径比大以及稳定性高的共形整流罩光学系统。
A fixed free-form lens array corrector is proposed in this paper to correct the dynamic aberration introduced by a conformal dome with large length-diameter ratio and large scanning angle.By designing the free-form surface shape and rotation angle of each lens of the lens array corrector,the dynamic aberration introduced by the large length-diameter ratio conformal fairing in different scanning angles is corrected.The experimental results show that the free-form lens array corrector can realize±50°scanning angle dynamic aberration correction for a conformal dome with a length-diameter ratio of 1.2.The new corrector has the advantages of both a dynamic corrector and a fixed corrector,and is suitable for a conformal dome optical system with a large scanning angle,a large length-diameter ratio and high stability.
