中文摘要：

与并列型复眼相比,重叠复眼有更高的光能量利用率和更高的灵敏度.该文从梯度折射率（GRIN）介质的光学特性出发,分析了GRIN介质在重叠复眼中的作用;参考生物解剖学中的测算结果,首次建立了重叠复眼的光学模型;通过对九个小眼进行光线追迹,分析了光接收器上的光线分布情况.

英文摘要：

Compound eye has the advantages of small volume,light weight,large FOV and high sensitivity. Compared with the apposition compound eye,superposition compound eye has the higher light efficiency, and higher sensitivity. The characteristic of the GRIN is introduced; the function of the GRIN medium in the superposition compound eye is studied in detail, it is the first time that the optical model of superposition compound eye was built ; by the ray tracing process of the nine ommatidia, the emergent light situation is studied, then the ray distributing on the receptor is achieved.
