| 摘要 |
A wide FOV imaging system ( 10 ) includes an objective lens ( 14 ), a convergent reflective element ( 18 ) positioned proximate an intermediate image ( 16 ) formed by the objective lens, and a re-imaging lens ( 20 ) for re-imaging the intermediate image. The present invention significantly improves image fidelity while minimizing optical components by utilizing a convergent reflective element proximate the intermediate image to reverse the propagation of aberrations produced by the objective lens ( 14 ) to, as a result, significantly cancel or reduce the aberrations contributed by the re-imaging lens.
