摘要:	本論文為大視角與高解析度近紅外線偵搜望遠光學系統設計，本偵搜望遠光學系統由一顆單中心物鏡、760 個相同目鏡及 760 個相同數位攝影鏡頭所組成。首先將單中心物鏡、目鏡和數位攝影鏡頭分別單獨設計，一顆單中心物鏡與一顆目鏡結合為望遠鏡系統，而一顆單中心物鏡與 760 顆目鏡結合為一群望遠鏡系統，共有 760 組望遠鏡系統，最後再將每一組望遠鏡系統與 760 個數位攝影機結合為偵搜望遠光學系統。本紅外線偵搜望遠光學系統，所偵測紅外線波長範圍為 750 nm 到 1100 nm，光學系統全視角要求範圍水平方向與垂直方向分別為 100度 × 30度且共有 760 台微型攝影機，每一台攝影機的感測器長與寬畫素數目為 3840 ×2160，共 829 萬畫素，畫素大小為 2 μm × 2 μm，每一台攝影機所對應紅外線偵搜望遠系統長與寬全視角範圍為2.614度(??) × 1.47度(V)，可得在感測器上每一畫素之角度解析度(IFOV, Instaneous Field of View)為 11.88 μrad，約為 0.04分(arc min)。已知人眼解析度為 1分本紅外線偵搜望遠系統設計之角度解析度為人眼 25 倍，總畫素數目為 63 億畫素。;This paper presents the optical design of a near infrared (NIR) surveillance system with wide angle and high resolution. The NIR surveillance optical system consists of a monocentric objective lens, 760 identical eyepiece lenses, and 760 identical digital cameras. The objective lens, eyepiece lenses, and digital cameras are designed separately. A combination of one monocentric objective lens and one eyepiece lens forms a telescope system, and a combination of one monocentric objective lens and 760 eyepiece lenses forms a cluster of telescope systems. There are a total of 760 sets of telescope systems, which are further integrated with 760 digital cameras to create the surveillance optical system. The infrared surveillance optical system detects near infrared (NIR) wavelengths ranging from 750 nm to 1100 nm. The required full field of view of the optical system is 100° in the horizontal direction and 30° in the vertical direction, respectively. There are 760 micro-cameras in total, and each camera has a sensor with a resolution of 3840×2160 pixels, totaling 8.29 million pixels. The pixel size is 2 μm × 2 μm. The corresponding full field of view of the near infrared surveillance system for each camera is 2.614°(H) × 1.47°(V). Therefore, the angular resolution (Instantaneous Field of View, IFOV) of each pixel on the sensor is 11.88 μrad or approximately 0.04 arc minutes. Given that the human eye has a resolution of 1 arc minute, the designed angular resolution of the infrared surveillance system is 25 times higher than the human eye. The total number of pixels is 6.3 billion
