Garnering inspiration from biological compound eyes, artificial vision systems boasting a vivid range of diverse visual functional traits have come to the fore recently. However, most of these artificial systems rely on transformable electronics, which suffer from the complexity and constrained geometry of global deformation, as well as potential mismatches between optical and detector units. Here, we present a unique pinhole compound eye that combines a three-dimensionally printed honeycomb optical structure with a hemispherical, all-solid-state, high-density perovskite nanowire photodetector array. The lens-free pinhole structure can be designed and fabricated with an arbitrary layout to match the underlying image sensor. Optical simulations and imaging results matched well with each other and substantiated the key characteristics and capabilities of our system, which include an ultrawide field of view, accurate target positioning, and motion tracking function. We further demonstrate the potential of our unique compound eye for advanced robotic vision by successfully completing a moving target tracking mission.

使用半球形纳米线阵列的超宽视场针孔复眼用于机器人视觉


受生物复眼的启发，具有多种视觉功能特征的人工视觉系统最近脱颖而出。然而，这些人工系统大多数依赖于可变换的电子器件，这些电子器件受到全局变形的复杂性和受限几何形状以及光学和探测器单元之间潜在的不匹配的影响。在这里，我们提出了一种独特的针孔复眼，它将三维打印的蜂窝状光学结构与半球形、全固态、高密度钙钛矿纳米线光电探测器阵列相结合。无透镜针孔结构可以采用任意布局进行设计和制造，以匹配底层图像传感器。光学模拟和成像结果相互匹配，证实了我们系统的关键特性和功能，包括超宽视场、精确的目标定位和运动跟踪功能。通过成功完成移动目标跟踪任务，我们进一步展示了我们独特的复眼在先进机器人视觉方面的潜力。
