Abstract: 본 발명은 부경 외곽에 형성된 환형 거울과 주경으로 정렬 광학계를 구성하여 대구경 반사 망원경의 전체 광경로에 대한 광학적 정렬상태를 점검한다. 상기 환형 거울에서 반사된 광선의 광파면과 주경의 특정 대역 표면형상과 일치하도록 널 시스템으로 설계한다. 이와 같은 널 정렬 시스템은 부경 외곽에 환형의 소형 널 반사경을 사용하므로 전체적인 무게가 가벼울 뿐 아니라 외형도 줄어드는 장점이 있다.

Abstract: In a method for acquiring and processing an omnidirectional panorama image at a high update rate, each of first to fourth wide viewing angle sensors (10-1, 10-2, 10-3, 10-4), which covers each of four 90°sections divided from a 360° omnidirectional section, acquires six sectional images (1, 2, 3, 4, 5, 6) divided from a 95° section, and applies a weighting function to the six sectional images (1, 2, 3, 4, 5, 6) to convert the six sectional images (1, 2, 3, 4, 5, 6) into section continuous images (1-1, 1-2, 1-3, 1-4, 1-5, 1-6) without overlap sections through re-matching. Next, the weighting function is applied to sections overlapped among a total of four section continuous images to create a 360° panorama image (C) having no overlapped sections through the re-matching. Therefore, according to a scanning optical system (1) of the present embodiment, a higher-resolution image can be acquired at a higher rate in a simple structure when being compared with a scheme that a rotating device or a planar detector is used together with a sensor.

Abstract: A multi-section view image acquisition type infrared wide-angle camera with a function of non-uniformity correction according to the present invention includes: a scanning mirror (70) which acquires a field of view more than an angle of 95 degrees by forming an image of each frame with six scanning images (a-1, a-2, a-3, a-4, a-5, a-6) through rotation divided into six stages; a re-imaging optical system which allows the scanning mirror (70) and a cold stop (11) to make an image to enable the effective blocking of adjacent column spill light and the optimization of the size of the scanning mirror; a field stop (60) which is provided on an infrared path to enable the blocking of spill light and the adjustment of transmittance; and a black body corrector which allows the scanning mirror to face the reference plane of a black body (85) while the scanning mirror returns to a starting point after a front image is acquired by rotating the scanning mirror (70). Thus, a clear image to which non-uniformity correction on a detector is applied can be obtained without securing a separate optical path for non-uniformity correction or applying an optical/mechanical mechanism. In particular, an optical system with a long focal distance can be realized while providing a wide-angle field of view to eliminate the disadvantages of a fish-eye type wide-angle optical system, thereby easily detecting and identifying a target.
