본 논문에서는 Q-polynomial을 이용한 Korsch 망원경의 비구면 반사경 공차 분석을 진행하였다. 고해상도 인공위성의 비구면 반사경은 고정밀 제작이 요구되어 품질을 평가하기 위한 공차 분석이 중요하다. 따라서 비구면을 각 계수항들이 독립적인Q-polynomial로 표현하고 Korsch 망원경 광학계의 공차 분석을 진행하였다. 또한 비구면 반사경에 형상 오차를 Zernike fringe sag로 부여하여 공차 분석하고 두 결과를 비교하여 Q-polynomial으로도 공차 분석할 수 있음을 확인하였다.
Abstract
In this paper, we study the analysis method for the aspherical tolerance of a Korsch telescope using a Q polynomial. It is important to analyze the tolerances for evaluating quality in high-precision fabrication of aspherical reflectors for high-resolution satellites. Thus we express the aspheric surface in terms of a Q polynomial in which each coefficient term is composed independently, and analyze the tolerance of a Korsch telescope. We also analyze the tolerance using Zernike fringe sag, which expresses the shape error of an aspherical mirror. By comparing the two results, we confirm that the Q-polynomial method can be used to analyze an aspherical mirror.
