摘要： A camera (40) is mounted on a gimbal (44) inside a missile (30) and views forwardly through a transparent, generally conical front dome or ogive (70). An optically refractive corrector (72) is mounted in front of the camera lens (42) for integral movement therewith. The corrector (72) has a least one conical surface segment (74a,74b) which is dimensioned to reverse optical conical deformation created by the dome (70). The conical deformation includes little or no refractive power in a plane defined by the axis (38) of the dome (70) and the look axis (46) of the camera (40) and gimbal (44), and progressively varying one-dimensional refraction perpendicular to this plane. Variables including the apex angles ( alpha 1, alpha 2) of cones (76,78) which define the surfaces (74a,74b), the angle ( alpha 3) between the axes (76b,78b) of the cones (76,78), the distances (D1,D2) between the apices (76a,78a) of the cones (76,78) and the center (74c) of the corrector (72), the tilt angle ( alpha 5) and the index of refraction of the corrector (72) provide sufficient degrees of freedom to enable a best fit solution which substantially reverses the conical deformation created by the dome (70).

摘要： A multiple field of view sensor lens assembly suitable for inclusion in an infrared imaging system. The lens assembly includes a rotatable telescope 10 for providing first and second fields of view for the sensor, the first field of view being along a first axis thereof L and the second field of view being along a separate second axis T. A servo mechanism 30 is included for rotating the telescope 10 from a first orientation at which the first axis is aligned with the optical axis to a second orientation at which the second axis is aligned with the optical axis. In a preferred embodiment the inventive lens assembly is disposed to provide fields of view in opposing directions along the first axis L, and a third field along the second axis T.
