Abstract

To design a wide-field two-mirror system, the system must feature an off-axial field, to avoid ray obstruction and field screening by the secondary mirror. The off-axial aberrations of the system cannot be corrected sufficiently, though, because there are only a few design parameters. The present study designs an improved off-axial-field two-mirror system using a decentered aperture stop.

넓은 시야를 가지는 2반사광학계를 설계하기 위하여서는 제2거울에 의한 광선의 차폐와 시야 가림이 없도록 비축시야를 사용하여야 한다. 그러나 이러한 2반사경계에서는 설계변수가 적어 비축수차를 충분하게 보정할 수 없었다. 이 연구에서는 조리개를 편심시켜 보다 성능이 개선된 비축시야 2반사광학계를 설계하였다.
