  Conformal imaging systems are confronted with dynamic aberration in optical design processing.In classical optical designs,for combination high requirements of field of view,optical speed,environmental adaption and imaging quality,further enhancements can be achieved only by the introduction of increased complexity of aberration corrector.In recent years of computational imaging,the adaptive coded apertures techniques which has several potential advantages over more traditional optical systems is particularly suitable for military infrared imaging systems.The merits of this new concept include low mass,volume and moments of inertia,potentially lower costs,graceful failure modes,steerable fields of regard with no macroscopic moving parts.Example application for conformal imaging system design where the elements of asset of binary coded aperture masks are applied are optimization designed is presented in this paper,simulation results show that the optical performance is closely related to the mask design and the reconstruction algorithm optimization.As a dynamic aberration corrector,a binary-amplitude mask located at the aperture stop is optimized to mitigate dynamic optical aberration when the field of regard changes and allow sufficient information to be recorded by the detector for the recovery of a sharp image using digital image restoration in conformal optical system.
