Abstract
An optical correction technique which utilizes a pair of toroidal optical elements which are translated axially to provide dynamic correction of astigmatic aberrations induced by conformal/aspheric domes and windows as a function of sensor gimbal angle. This correction technique provides dual axis, variable optical power correction within the dynamic operation of gimballed optical sensors, and is particularly suited to correction of aberrations introduced by conformal/aspheric domes and windows used in both missile and airborne fire control systems.
