초록

함정용 전자광학추적장비의 센서부에서 해수면반사파에 의해 발생하게 되는 영상추적간섭 현상을 최소화하고자 전방향성, 점진적인 굴절률 및 표면 요철구조를 갖는 산화아연에 플루오르화마그네슘을 코팅한 반사방지막을 전자빔 증착 장비를 통해 제작하였다. 최적화된 산화아연에 플루오르화마그네슘을 코팅한 반사방지막은 기존의 산화아연 반사방지막과 비교하여 점진적인 굴절률 변화에 따라 표면 프레넬 반사를 최소화하고 이를 통해 전자광학추적장비의 영상추적간섭 현상을 제거하는 장점이 있다. 본 실험을 통해, 산화아연에 플루오르화마그네슘을 코팅한 반사방지막이 다양한 전자광학장비의 반사방지막으로써 적용이 가능함을 확인하였다.

An omni-directional, graded-index and textured ZnO nanorods with $MgF_2$ anti-reflective(AR) coating films for the electro optical tracking system(EOTS) by e-beam evaporation method are presented. we achieved that the graded index structure can minimize image tracking interference of EOTS which is comparable to a general AR coating films. Optimized ZnO nanorods with $MgF_2$ AR coating films lead to decreasing Fresnel reflection by gradient refractive index. According to our experiment results, ZnO nanorods with $MgF_2$ AR coating films can be used for various electro optical system to improve the optical performance.
