Compound eye cameras are a vital component of bionics. Compound eye lenses are currently used in light field cameras, monitoring imaging, medical endoscopes, and other fields. However, the resolution of the compound eye lens is still low at the moment, which has an impact on the application scene. Photolithography and negative pressure molding were used to create a double-glued multi-focal bionic compound eye camera in this study. The compound eye camera has 83 microlenses, with ommatidium diameters ranging from 400 μm to 660 μm, and a 92.3 degree field-of-view angle. The double-gluing structure significantly improves the optical performance of the compound eye lens, and the spatial resolution of the ommatidium is 57.00 lp mm. Additionally, the measurement of speed is investigated. This double-glue compound eye camera has numerous potential applications in the military, machine vision, and other fields.
复眼相机是仿生学的重要组成部分。复眼透镜目前应用于光场相机、监控成像、医用内窥镜等领域。然而,目前复眼透镜的分辨率仍然较低,这对应用场景产生了影响。本研究采用光刻和负压成型技术制作了一种双胶合多焦点仿生复眼相机。该复眼相机有83个微透镜,小眼直径在400μm至660μm之间,视场角为92.3度。双胶合结构显著提高了复眼透镜的光学性能,小眼的空间分辨率为57.00 lp/mm。此外,还对速度测量进行了研究。这种双胶合复眼相机在军事、机器视觉等领域有诸多潜在应用。
