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.
Abstract
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,fast-moving targets.Inspired by the sensitivity of compound eyes possessed by insects to moving objects,we prepared a single-layer bionic compound eye with five ommatidia,each consisting of a Fresnel lens.Using femtosecond laser two-photon 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 high-quality images and be used to track moving targets.
