  • 색본 연구에서는 중심이 차폐된 광학계를 고려하여 중심차폐와 입사광의 가우시안 진폭의 단락된 정도에 따른 광학계의 성능을 평가하기 위해 중심 spot 분포와 에너지 분포를 조사하였다. 광학계에서 중앙 차폐 반경의 크기가 증가함에 따라 상면에서 중심 spot의 반경은 점점 작아지며, 가우시안 진폭의 단락된 정도가 증가할수록 상면에서 중심 spot의 반경은 증가하였다. 또한 광학계의 중앙 차폐된 영역과 가우시안 진폭의 단락된 정도가 증가할수록 초점이동에 따른 초점심도는 증가하였으며, 중심 spot에서의 encircled energy는 감소되었다. 이러한 결과로부터 중앙 차에가 증가할수록 가우시안 인자의 영향이 작음을 알 수 있었다. 이러한 연구결과는 대구경 반사광학계의 개발에 사용될 것이다.

  • Central motion techniques are to mention the central-motion by the limpness motion function and limpness sensory unit function on the body. Central body motion is consisted of the limpness central function by the central body system. To evaluate the signal of central body motion, we are investigated a limpness value of the central function by the central body function on the static state. The concept of limpness motion function was checked the reference of limpness motion signal and limpness sensory signal by the central motion body. For assessment on the limpness sensory variation of the maximum and average in terms of central motion from the static function, and limpness value that was a limpness value of the vision condition of the Vi-${\lambda}_{MAX-AVG}$ with $8.71{\pm}-3.2units$, that was a limpness value of the vestibular condition of the Ve-${\lambda}_{MAX-AVG}$ with $3.05{\pm}-6.52units$, that was a limpness value of the somatosensory condition of the So-${\lambda}_{MAX-AVG}$ with $2.4{\pm}1.9units$. The static sensory motion was made mention of check out at the condition of the limpness sensory unit motion for the comparable values of limpness central motion that was expressed the analysis capacity by the limpness nerve system. Limpness sensory system will be to propose of the minute motion by static central motion situation and was to imply a limpness motion data of static body sensory function.
