论文摘要
在昆虫中发现的复合眼睛为微型成像系统提供了有趣的生物灵感来源。受这种昆虫眼结构的启发，我们展示了由平坦的多级衍射微片阵列启用的超薄阵列相机，用于超分辨率可见成像。我们通过实验证明，Microlens阵列可以在可见带（450nm至650nm）中实现较大的填充因子（六角形关闭填料，厚度为120um），厚度为2.6UM和衍射限量限制（Strehl比= 0.88）。我们还通过计算合并阵列中的1600张图像来证明超分辨率成像，分辨率改进了1.4倍。
Compound eyes found in insects provide intriguing sources of biological inspiration for miniaturized imaging systems. Inspired by such insect eye structures, we demonstrate an ultrathin arrayed camera enabled by a flat multilevel diffractive microlens array for super-resolution visible imaging. We experimentally demonstrated that the microlens array can achieve large fill factor (hexagonal close packing with pitch=120um), thickness of 2.6um, and diffraction-limited (strehl ratio = 0.88) achromatic performance in the visible band (450nm to 650nm). We also demonstrate super-resolution imaging with resolution improvement of 1.4 times by computationally merging 1600 images in the array.
