微结构集成光纤仿生复眼的研究

Compound eye compared with monocular eye has the advantages of high sensitivity, large field and so on. Thus the artificial compound eye was widely used in weapon's precise guidance system such as infrared detection, early warning satellites, ships searching and tracking and in civilian industries such as large infrared telescope, miniature cameras and others. As optical fiber has small size, light weight, immunity to electromagnetic interference, it was used in artificial compound eye and with good results. But it is difficult to combine the devices and with large optical loss, not easy to manufacture. As mentioned above, design a practical, low loss system is a key to promote the practical application of artificial compound eye. As far as we know, there is no all-fiber artificial compound eye. We original proposed a micro-structure integrated all fiber artificial compound eye. Biomimetic cornea and crystalline cone will be manufactured by integrated fiber bundle which has micro lens at its end face. The optical signal can be focus at once and the device can be directly connected with detector. The system has many advantages like not easy damaged, easy to manufacture, highly integrated, high transmission efficiency and stable optical properties, etc.. We will focus on the artificial compound eye's fabrication, structural optimization, optical characteristics and carry out the experimental study of the actual device.

复眼与单眼相比具有灵敏度高、视场角大等优点，因此仿生复眼在红外探测、预警卫星、舰艇搜索和跟踪等武器精确制导系统以及大型红外望远镜、微型照相机等民用工业得到广泛应用。光纤具有体积小、重量轻、抗电磁干扰等特点，因而近几年出现了用光纤制作仿生复眼传光器件的研究，取得了较好的效果。但这些研究存在器件组合对准难度大、光损耗大、不易实用化等不足，因此设计一种易于实用化、低损耗的仿生复眼，是推动仿生复眼实际应用的关键技术。据我们所知，目前还没有全光纤仿生复眼。本项目原创性地提出了一种微结构集成光纤仿生复眼，这种仿生复眼用端面经过微加工的集成光纤束制造仿生角膜、晶椎使光信号一次聚焦，且可直接与光纤探测器连接，系统具有不易损坏、加工方便、高集成度、高传输效率、光学特性稳定等优点。我们将围绕这种全光纤仿生复眼的制作、结构优化及传光特性等内容进行研究，并开展实际器件的实验研究。
