Miniaturized bionic compound eyes featured with multi-aperture imaging have potential applications in the areas of micro opto-electro-mechanical-system. In this manuscript, we present a novel structure of the bionic compound eye with multiple focal lengths consists of an array of individual lenses with 1000 µm diameter. The simulation results of the designed multifocal bionic compound eye (MBCE) with two focal lengths of 190 mm and 44.4 mm demonstrate excellent two-order focusing abilities. Moving mask exposure technology was used to fabricate the designed MBCE with the corresponding imaging experiments conducted to validate the two-order imaging ability of the fabricated MBCE. Experimental results revealed that the developed structure has potential applications in diverse optical imaging systems such as three-dimensional imaging and real-time detection of unconfined or fluctuating targets.
微型仿生复眼具有多孔径成像功能，在微光电机械系统领域有潜在的应用。在本文中，我们提出了一种由直径为 1000μm 的单个透镜组成的阵列组成的具有多个焦距的仿生复眼的新结构。设计的具有两个焦距 190mm 和 44.4mm 的多焦点仿生复眼（MBCE）的模拟结果表明其具有出色的二级聚焦能力。采用移动掩模曝光技术制造了设计的 MBCE，并进行了相应的成像实验以验证所制造的 MBCE 的二级成像能力。实验结果表明，所开发的结构在三维成像和无约束或波动目标的实时检测等多种光学成像系统中有潜在的应用。
