In order to enhance the imaging quality of the staring conformal optical system, a static correction method which combines the optimized inner surface of the conformal dome and fixed correctors with Zernike Fringe Sag surfaces is proposed. On the base of the relationship between the parameters of dome and the shift in the direction of a ray as it passes through a conformal dome, the parameters of the inner surface of the dome are projected, which reduce some aberrations of the conformal optical system. Then, the correspondence between the Zernike Fringe polynomial terms and aberrations is used to build the fixed corrector with Zernike Fringe surfaces. Based on this method, a staring conformal optical system is designed, whose F is 1, focal length is 30 mm, the field of view is ± 35°. The characters of the aberrations are analyzed before and after correction. The result shows that this method has a good effect on correcting the main aberrations, and the modulation transfer function (MTF) of optical system is higher than 0.748 at the spatial frequency of 17 lp/mm across the entire field of view. The imaging quality is favorable.
