| Abstract: | A kind of optical annular pupil filters with equal width zones is designed and its superresolving properties are studied. The effects of the annular number and the central radius on the Strehl ratio, the superresolving power and the intensity of sidelobe are analyzed and the optimization problem of the annular number and the central radius is discussed. It is shown that the properties are different of the two pupils with the odd annular number and the even annular number and that the pupils have better superresolving power when the annular number is 1 and 2 respectively. |
