  • 현재 컴퓨터 조작하는 방식은 입력장치인 키보드로 조작하는 CUI, 마우스로 조작하는 GUI가 있지만 키보드와 마우스를 사용하기 불편한 장소나 불편한 사람이 동작과 음성만으로 컴퓨터를 조작하는 NUI를 구축하여 보다 나은 컴퓨팅환경을 제공하고 새로운 형식의 콘텐츠를 제공할 수 있는 기틀 마련한다.

  • We are developing an optomechanical design of infrared telescope for the CubeSat and Unmanned Aerial Vehicle (UAV) which adapts the Linear Astigmatism Free- Three Mirror System in the confocal off-axis condition. The small entrance pupil (diameter of 40 mm) and the fast telescope (f-number of 1.9) can survey large areas. The telescope structure consists of three mirror modules and a sensor module, which are assembled on the base frame. The mirror structure has duplex layers to minimize a surface deformation and physical size of a mirror mount. All the optomechanical parts and three freeform mirrors are made from the same material, i.e., aluminum 6061-T6. The Coefficient of Thermal Expansion matching single material structure makes the imaging performance to be independent of the thermal expansion. We investigated structural characteristics against external loads through Finite Element Analysis. We confirmed the mirror surface distortion by the gravity and screw tightening, and the overall contraction/expansion following the external temperature environment change (from -30℃ to +30℃).
