摘　　要：传统曲面仿生复眼中继系统需要承担大视场子眼拼接造成的弯曲像面转换成平像场的任务,给系统设计带来一定难度。针对上述问题提出一种大视场复眼平像面拼接排列的方法,并对该方法进行数学描述。通过构建子眼个数、系统总视场角以及后续合理选取光中继系统参数之间的平衡模型,重点分析中继系统景深与复眼拼接像面光程差之间的关系,得出复眼平像面的拼接方式产生的光程差在典型光中继系统的可接受景深范围内,可以有效地降低中继光学系统设计压力的结论。并基于上述理论设计一种单子眼的视场为16°、整体视场为96°的复眼光学系统进行实践验证。系统最终实现畸变小于2%,传递函数在中心视场达到衍射极限,边缘视场接近衍射极限的良好像质,证明了该拼接理论可行。The conventional curved bionic compound eye relay system is required to undertake the task of converting the curved image plane caused by the splicing of large-field subeyes into a flat image field,which poses certain difficulties to the system design.A method was proposed for the splicing arrangement of the flat image plane of the large-field compound eyes,and the method was described mathematically.By constructing a balanced model between the number of subeyes,the total field of view of the system and the subsequent reasonable selection of the optical relay system parameters,the relationship between the depth of field of the relay system and the optical range difference of the spliced image plane of the compound eye was analysed,and it was concluded that the optical range difference generated by the splicing method of the compound eye flat image plane was within the acceptable depth of field of a typical optical relay system,which could effectively reduce the design pressure of the relay optical system.Based on the above theory,a compound eye optical system with a field of view of 16° for a single subeye and an overall field of view of 96° was designed for practical verification.The system finally achieves an aberration of less than 2%,the transfer function reaches the diffraction limit in the central field of view and the edge field of view is close to the diffraction limit with good image quality,which proves that splicing theory is feasible.
