【摘要】：提出了一种光学合成孔径成像系统,该系统将多个平面反射镜前置在主成像镜头之前,与主成像镜头共同组成光学系统的"主镜",通过对同一目标的多个视场通道的收集成像到主镜头的焦平面上,获得多个同一目标的像,之后再经过小透镜阵列将这些多个同一目标的像准直,在其后用大孔径的光学系统收集准直后的多个同一目标的不同通道的光束,获得同一目标的合成孔径图像.主镜头的多个视场观测同一目标,各个视场称之为不同的通道.该方案采用平面镜拼接形成主镜,平面镜可用于组装成大口径的望远镜并获得高分辨率图像,使得望远镜得到轻量化,并进行实际的光学系统和实验验证.外场实验获得了多幅外景图片,证明所获多通道图片为超分辨图像.
[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.
