초록
비정형(anamorphic) 렌즈가 적용된 적외선 광각 카메라 광학계를 제안하고 제작을 통해 그 유용성을 입증하였다. 개발된 적외선 카메라는 비정형 렌즈를 이용하여 수평방향에 대해서는 100도 이상의 넓은 시계를 제공하면서 수직방향에 대해서는 수평시계보다 큰 배율을 갖게 함으로써 증가된 해상도를 통해 장비의 광역 감시 및 탐지 능력을 동시에 향상시키는 특징을 갖는다. 또한 광기구적 자동 비열화 방법을 제안하고 시스템에 적용하여 그 성능 및 활용성을 확인하였다.
Abstract
A system of infrared camera optics with wide field of view and anamorphic lenses is proposed, and its validity verified throughmanufacture. The infrared camera produced provides a wide field of view of over 100 degrees in the horizontal direction, andan even greater magnification in the vertical direction. As a result, the system can have a wider surveillance range and improveddetection ability at the same time. In addition, a new optomechanical automatic athermalization mechanism is proposed andapplied to the infrared camera. Its performance and utility is proved through testing.
