摘　　要：生物复眼具有良好的光学特性,如视野大、体积小、无像差、对运动物体敏感等。而对运动物体敏感对昆虫十分重要,如飞行昆虫觅食时需要追逐小型、快速移动的目标等。受昆虫复眼对运动物体敏感的启发,制备了具有5个小眼的单层复眼,每个小眼由1个菲涅耳透镜构成。通过飞秒激光双光子聚合加工技术和软光刻复写技术,制备出具有高精度和可重复性的柔性仿生复眼。实验结果表明,该仿生复眼可以获得可辨识的图像并且可以用于追踪运动目标。Biological compound eyes have excellent optical properties,including large field of view,small size,no aberrations,and sensitivity to moving objects.Sensitivity to moving objects is crucial for flying insects that chase small,fastmoving targets.Inspired by the sensitivity of compound eyes possessed by insects to moving objects,we prepared a singlelayer bionic compound eye with five ommatidia,each consisting of a Fresnel lens.Using femtosecond laser twophoton polymerization processing technology and soft lithography technology,a flexible bionic compound eye with high accuracy and repeatability was prepared.Experimental results show that the prepared bionic compound eye could obtain highquality images and be used to track moving targets.
