Abstract
Description
여기서, 상기 집광부(107a)의 재질은 굴절률 1.5~1.55 사이를 가지는 플라스틱 사출물이며, 집광부(107a)의 추가 곡률은 주곡률의 1/2 미만으로 한정한다.
즉, 굴절의 기본법칙은 수학식 1과 같이 스넬의 법칙에 따라 발생하며, 수학식 1을 이용하여 외부돔을 통과한 빛의 출사각을 구할 수 있다.
일반적인 경우 돔의 외부 곡률이 r=5.8이고, 내부 곡률이 r=5.1인 경우, 스넬의 법칙에 따라 입사되는 빛이 돔의 안쪽에 존재하는 공기에서 돔의 내부면으로 이동할 때, 수학식 1에 대입한 결과, 1*sin(39.39)=1.5146*sin(출사각 1)출사각 1=24.77을 얻을 수 있고, 돔에서 상기 돔의 외부면으로 빛이 이동할 때 수학식 1에 대입한 결과, 1.5146*sin(21.62)=1*sin*(출사각 2)에서 출사각 2=33.92를 얻을 수 있다.
내부 면이 동일하다는 조건 하에서 외부 곡률을 추가했을 때에도 상기 출사각 1은 동일하며 상기 입사되는 빛이 외부 추가 곡률을 지날 때의 출사각은, 1.5146*sin(39.86)=1*sin(출사각 2)에서 출사각 2=76.1을 얻을 수 있다. 즉, 외부 곡률을 특정 부분에 추가하고, 외부 곡률에 맞는 입사각을 크게 함으로써 출사각을 크게 할 수 있다는 공식이 성립된다.
Claims (5)
- 내부를 밀봉하는 외장 부재인 하우징과, 상기 하우징 내에 설치되어 피검체를 조명하는 조명수단과, 상기 조명수단에 의해 조명되는 피검체의 광학상을 형성하는 촬상 광학계와, 상기 하우징에 결합되고 상기 조명수단에서 출사된 광 및 상기 촬상 광학계에 입사되는 광이 투과되는 투명 커버를 포함하는 캡슐형 내시경에 있어서:상기 투명 커버는,상기 촬상 광학계의 촬상각보다 크고 상기 조명수단의 최대 광 조사각보다 작은 범위 내에 형성되어, 상기 조명수단에서 출사되는 광 중 상기 촬상 광학계의 촬상 각을 벗어나는 손실부분의 광을 집광하여 상기 촬상각의 범위 이내로 굴절시켜 조사하는 집광부를 포함하는 캡슐형 내시경.
