The invention discloses a 360 degree large field of view integrated bionic compound eye, which is to fabricate a microconvex lens array with a curved surface fiber panel which is not inserted in the optical fiber, and separate the two. The microlens array is then bonded to the curved optical fiber panel with optical fiber inserted by the photosensitive resin. The other end of the optical fiber is connected with the ultraviolet light source. After light, the UV light is exposed to the light sensitive resin on the surface of the surface of the surface of the optical fiber surface and then baked, forming a bionic \crystal cone\ with the self aligned micro convex lens. Then the optical fiber is disconnected from the ultraviolet light source and connected to the photodetector, and the photodetector is placed inside the surface fiber panel. The curved optical fiber panel is spliced and closed to form a spherical 360 degree large field of view integrated bionic compound eye. Or directly prepare the optical fiber with a micro convex lens structure, then insert it into the surface fiber panel, and then connect the fiber to the photodetector. Finally, the surface fiber panel is spliced to form a spherical 360 degree large field of view integrated bionic compound eye. The bionic compound eye makes use of optical fiber to make a bionic \optic nerve\, the micro convex lens of the fiber end face is a bionic \cornea\, and a bionic \crystal cone\ is formed from the light sensitive material, the photodetector is a bionic \retina\ and a wireless communication with the external computer. The whole bionic compound eye has the characteristics of highly integrated, 360 degree large field of view, light weight, controllable size and wireless communication.

一种360°大视场集成仿生复眼(一)
本专利技术涉及光学仿生复眼领域,具体是一种360°大视场集成仿生复眼的制备。(二)
技术介绍
复眼是一种由很多小眼组成的眼睛,多出现于昆虫及甲壳类等动物之中。虽然一个小眼的辨识度十分有限,但许多小眼组合在一起组成的复眼在各方面的能力都要远远胜过人眼,比如,人眼每秒只能分辨24幅图像,而复眼则能达到成千上百,因此我们日常生活中拍打苍蝇往往是失败的。仿生复眼具有重量轻、体积小、灵敏度高、视场大的优点,虽然发展历史短,但是在军事、医学等领域都已有极好的表现。仿生复眼的结构主要分为平面型和曲面型等,平面型主要由微凸透镜平面阵列和光隔离层组成,曲面型则是微凸透镜曲面阵列和光隔离层。由于制作工艺受限,且制作成本的关系,目前的研究多以平面仿生复眼为多。然而曲面的仿生复眼的视角大于平面的仿生复眼,效果更好。曲面仿生复眼的制作一般是先采用滴液法或者曲面光刻技术在基底上做出微凸透镜阵列,再将其与波导阵列或光阑阵列对准耦合。美国Ki-HunJeong等人通过气压变化将平面PDMS微凸透镜阵列变为曲面PDMS微凸透镜阵列,成功得到曲面SU-8胶微凸透镜阵列。SU-8胶具有自聚焦效应,曝光后得到与透镜自对准的波导阵列。目前的人造仿生复眼,需要用聚合体材料在两个相邻的小眼之间构造保护用的透明墙,从而减少像元的重叠,以此获得较高的分辨率。光纤具有重量轻、体积小、抗电磁干扰、通信容量大、信号衰减小等优点,在信号传输系统中就像是动物视觉系统的视觉神经,因此在仿生复眼领域受到了高度重视。英国BAE系统公司于2007年提出的可用机载平台的多孔径成像系统采用 ...
