국문 초록
엑스선(X-ray)은 의료뿐만 아니라 산업에 광범위하게 사용되고 있다. 엑스선을 집광하기 위해 엑스선의 물질적 현상인 회절을 이용하는 소자, 반사를 이용하는 소자 등 다양한 방식의 광학소자가 사용되고 있다. 단일 모세관 광학소자는 직경이 매우 작은 모세관의 내부 전반사를 이용하는 소자로, 방사광의 빔라인뿐만 아니라 엑스선회절장치(XRD) 및 엑스선형광분석장치(XRF)의 집광소자로 활용범위가 매우 넓다. 단일 모세관 광학소자는 유리 모세관을 녹여 설계한 정확한 형상을 갖도록 직경을 조절해야 한다. 단일 모세관 광학소자의 광학적 성질은 모세관 광학소자의 형상에 매우 민감하게 의존하기 때문에 수십에서 수백 마이크로미터의 직경을 갖는 모세관을 매우 정확하게 측정해야 한다.
본 논문은 방사광 빔라인의 고해상도 영상을 이용하여 직경이 매우 작은 단일 모세관 광학소자의 직경을 정확하게 측정할 수 있는 방법을 제시한다. 영상의 공간분해능을 고려하면 1.32μm의 정밀도로 단일 모세관 광학소자의 직경을 정확히 측정할 수 있다.
