  • Dynamic aberration corrector for conformal windows
    Patent number: 5526181
    Abstract: A method and apparatus (30) for compensating for optical aberration created by a conformal window (60). The apparatus (30) comprises a one-dimensional corrector plate (32) for providing a varying amount of linear coma, first and second cylindrical lenses (34, 38) for providing a varying amount of astigmatism and a system for adjusting the corrector plate (32) and the lenses (34) and (38) to minimize the optical aberration created by the conformal window. The apparatus (30) of the present invention provides for correction of considerable amounts of optical aberration over a wide field of regard. The apparatus is simple in design, easy to install and cost effective.
