【摘要】：提出了一種光學合成孔徑成像系統,該系統將多個平面反射鏡前置在主成像鏡頭之前,與主成像鏡頭共同組成光學系統的"主鏡",通過對同一目標的多個視場通道的收集成像到主鏡頭的焦平面上,獲得多個同一目標的像,之后再經過小透鏡陣列將這些多個同一目標的像準直,在其后用大孔徑的光學系統收集準直后的多個同一目標的不同通道的光束,獲得同一目標的合成孔徑圖像.主鏡頭的多個視場觀測同一目標,各個視場稱之為不同的通道.該方案采用平面鏡拼接形成主鏡,平面鏡可用于組裝成大口徑的望遠鏡并獲得高分辨率圖像,使得望遠鏡得到輕量化,并進行實際的光學系統和實驗驗證.外場實驗獲得了多幅外景圖片,證明所獲多通道圖片為超分辨圖像.
[Abstract]:Put forward a kind of optical synthetic aperture imaging system, the system will be more than a plane mirror front before the main imaging lens, and imaging lens optical system composed of the "mirror", by collecting a plurality of imaging field channel on the same target to the focal plane of the main lens surface, multiple the same as the target, and then after the small lens array at a plurality of target image alignment, in the subsequent optical system for large aperture collection of collimated plurality of same target different channel beam synthetic aperture image to obtain the same goal. A number of field observations with a main lens each field goal, called different channels. The scheme adopts the plane mirror spliced into a mirror, the mirror can be used for assembling the large aperture telescope and obtain high resolution images, which are lightweight telescope optical system, and the actual Experimental verification. External field experiments have obtained a number of external images, which prove that the multichannel images are super-resolution images.
