摘要

提出了一种结合点胶和干相摩擦工艺的可拉伸生物激发复合（BIC）眼结构作为印刷光学元件。通过所述点胶方法形成半球形宏透镜，然后采用干相摩擦工艺将单层微颗粒排列到所述宏透镜的曲面上。这种分层结构在具有内在拉伸性的软材料中得到复制。微透镜阵列形成在宏观透镜的表面，并作为一个刚性岛，从而保持透镜的形状和分辨率，即使机械应变施加到整体层次结构和宏观透镜的形状被改变。

Stretchable bioinspired compound eye structures with curved microlens arrays via a dry-phase rubbing process.

A stretchable bioinspired compound (BIC) eye structure with a combination of dispensing and dry-phase rubbing processes is proposed as a printed optical component. A hemispherical macrolens is formed by the dispensing method, followed by a dry-phase rubbing process for arranging microparticles in monolayers onto the curved surface of the macrolens. This hierarchical structure is replicated in soft materials, which have intrinsic stretchability. A microlens array is formed on the surface of the macrolens and acts as a rigid island, thereby maintaining lens shape and resolution even though mechanical strain is applied to the overall hierarchical structures and the shape of the macrolens is changed.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
