Abstract

A novel alignment method that can be used for aligning the collimating mirror employed in a monochromator is described. In most of the spectrometer industry, the alignment of optical components such as a focusing mirror, a grating and a collimating mirror has been performed manually so far. In this paper, we use a matchedfilter based image correlation technique for measuring the accurate image position which is used for aligning the collimating mirror. The experimental results show that with the proposed scheme automatic alignment can be completed within 10 seconds.

본 연구에서는 현재 대부분 작업자에 의해 수동으로 이루어지고 있는 단색화장치 내 광학 요소간 광학정렬을 높은 반복도와 고속으로 수행할 수 있는 자동화 방안에 대해 논의하고자 한다. 단색 분광기의 시준거울 자동정렬을 위해 CCD센서를 이용한 위상이미지 상관기법을 핵심기술로 사용하였다. 실험결과 약 10초 내에 시준거울을 정밀하게 자동정렬 할 수 있다.
