There is difficulty. In particular, the camera installed to monitor the interior of the dark chamber of the facility has to accept the bright external image 21 and the dark chamber image 19 reflected through the glass window for chamber observation, so it is difficult to clearly interpret the desired image. This follows.
또한, 이러한 어려움을 개선하기 위해 카메라 외부에서 챔버 내부를 비추는 램프(lamp)를 설치하여도 이러한 현상은 크게 개선되지 않는다. In addition, even if a lamp for illuminating the inside of the chamber from the outside of the camera to improve this difficulty, this phenomenon is not greatly improved.
이에 본 발명은 상기 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 카메라가 받아 들이는 영상을 선별하여 원하는 명료한 영상만을 얻을 수 있도록 한 반사 영상 제거용 필터가 구비된 모니터 시스템을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and provides a monitor system having a filter for removing the reflection image to select the image received by the camera to obtain only the desired clear image. There is a purpose.
상기 목적을 달성하기 위한 본 발명에 따른 반사영상 제거용 필터가 구비된 모니터 시스템은, 상면에 관측용 유리창이 형성된 챔버;According to an aspect of the present invention, there is provided a monitor system including a filter for removing a reflection image, the chamber including an observation window formed on an upper surface thereof;
상기 관측용 유리창과 일정 거리만큼 떨어진 위치에 설치된 편광필터;A polarizing filter installed at a position separated by a predetermined distance from the observation window;
