摘要
An offset aperture gimbaled optical system comprises a gimbal and an optics assembly that is mounted on an inner gimbal and offset radially from an axis of symmetry (and rotation axis) of a conformal dome. An optical corrector adjacent the inner surface of the conformal dome encompasses the field-of-view of the optics assembly as the inner gimbal rotates about its rotation axis. The corrector is fixed with respect to the inner gimbal's rotation axis while it rotates about the axis of symmetry. The optical corrector comprises an aspheric transparent arch having an optical corrector shape and position responsive to a shape of the conformal dome at the offset position of the optics assembly. In different applications, the offset aperture provides for reduced optical aberrations and improved utilization of the available packaging volume to accommodate multiple offset aperture optics assemblies.
