Abstract

We present an attractive real time in-vivo endoscopic microscope with a resolution of submicron, in which two kinds of optical correcting plates are inserted to eliminate higher order spherical aberration and field curvature. And, since the conventional objective lens is replaced to GRIN lenses with diameter of 1 mm, the above endoscopic microscope can be effectively utilized to invade minimally for live animals.

본 논문에서는, 2가지 종류의 광학보정소자에 의해 고차의 구면수차와 상면만곡이 보정된, 서브마이크론 (1.0 ${\mu}m$이하)의 광학 분해능을 갖는 매력적인 실시간 in-vivo 내시현미경을 소개한다. 덧붙여 소개된 내시현미경은 대물렌즈부의 직경이 1 mm인 GRIN (Gradient Index) 렌즈로 구성되어 있기 때문에 최소 침습적인 장점도 갖고 있다.
