Micro-lens array, an artificial compound eye vision system, provides a wide field of view and multi-perspective view. However, it has not been adopted as a computer vision application due to its limited visible range and high optical interference. In this research, a novel fabrication method for the flexible polydimethylsiloxane micro-lens array with a polytetrafluoroethylene light screen-aperture integrated layer was established by the simple protrusion method. The integrated layer provided longer visible range by one meter while maintaining the wide field-of-view of 100 °. The resulting images were used for obtaining depth information of a target as an example and for analyzing the rectangular and hexagonal arrangements of the micro-lenses for the future applications. With the improved visual range, wide field-of-view and flexibility, the fabricated micro-lens array can be applied to the small and curved CMOS image sensors in the future.
微透镜阵列，一种人工复眼视觉系统，提供了广阔的视野和多角度视图。然而，由于其可见范围有限和高光学干扰，它尚未被应用于计算机视觉领域。在这项研究中，通过简单的凸起方法建立了一种带有聚四氟乙烯光筛-孔径集成层的柔性聚二甲基硅氧烷微透镜阵列的新型制造方法。该集成层在保持 100°宽视场的同时，将可见范围延长到了 1 米。所得到的图像被用于获取目标的深度信息，并分析微透镜的矩形和六边形排列，以用于未来的应用。通过提高可视范围、宽视场和灵活性，所制造的微透镜阵列将来可以应用于小型和弯曲的 CMOS 图像传感器。
