Dynamic Aberration Correction for Conformal Dome Based on Free-Form Lens Array
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.
