초록

광학계는 매우 다양한 용도로 사용되고 있기 때문에 유사한 구성의 광학계에서도 활용목적과 주어진 광학사양에 따라 다양한 설계가 존재한다. 하지만 광학수차는 광학계의 구조와 광학사양 모두에 영향을 받으므로 수차분석만으로는 광학설계의 고유한 특성을 파악하기 어렵다. 이 연구에서는 무차원의 설계변수를 사용하여 광학사양과 무관하게 광학설계의 수차특성을 파악하는 방법을 연구하고, 예시로서 서로 다른 용도와 사양을 가지는 4종의 triplet 설계를 분석하였다.

Since optical systems are used for various applications, there are many designs, depending on the purpose and optical specifications, even though they have similar formations. Optical aberrations of a system are affected by both structure and specifications. Thus, it is very difficult to find the special characteristics of an optical design by using aberration analysis only. Regardless of specifications, a new method to investigate the aberration characteristics of an optical design is presented, using dimensionless design parameters. Four kinds of triplet designs with different applications and specifications are analyzed as examples.
