The traditional imaging technologies, such as two-dimensional imaging, have not been able to meet people's needs for higher technology. Inspired by the characteristics, such as small size, sensitivity to moving targets and large field of view, researchers began to study bionic compound eyes. In this paper, a hemispherical mounting surface with through holes to set the compound lens array is fabricated by 3-D printing technology. More than one hundred small lenses are mounted on the 3-D printed hemispherical surface to form a bionic curved compound eye, which is then integrated with an optical relay system and an CMOS imaging sensor to form a rather compact bionic compound eye camera. The addition of the optical relay system solves the problem that the mismatch between the curved focal plane formed by the curved compound eye and the flat focal plane of the CMOS imaging sensor. By employing this method, we design and analyze the curved lens array and optical relay system, and perform the related optical performance tests on the fabricated bionic curved compound eye imaging system. The results show that a good image quality can be achieved. The formed bionic compound eye imaging prototype system rather compact and has a weight of only 121 g, a volume of 34 mm × 44 mm × 80 mm, and a field of view of 120° × 120°. This system has great potential and value in military, medical, and engineering applications.

紧凑型仿生复合眼相机,可在大视野中成像

诸如二维成像的传统成像技术不能满足人们对更高技术的需求。受诸如小尺寸,对移动目标的敏感性和大视野等特性的启发,研究人员开始研究仿生复眼。在本文中,通过3-D打印技术制造了一个带有通孔的半球形安装表面,用于设置复合透镜阵列。在3-D打印的半球表面上安装了一百多个小透镜,以形成仿生弯曲复眼,然后将其与光中继系统和CMOS成像传感器集成在一起,以形成相当紧凑的仿生复眼相机。光学中继系统的增加解决了由弯曲的复眼形成的弯曲的焦平面与CMOS成像传感器的平坦的焦平面之间的不匹配的问题。通过这种方法,我们设计和分析了曲面透镜阵列和光学中继系统,并在制造的仿生曲面复眼成像系统上进行了相关的光学性能测试。结果表明可以实现良好的图像质量。形成的仿生复眼成像原型系统相当紧凑,重量仅为121 g,体积为34 mm×44 mm×80 mm,视场为120°×120°。该系统在军事,医疗和工程应用中具有巨大的潜力和价值。并在制作的仿生曲面复眼成像系统上进行相关的光学性能测试。结果表明可以实现良好的图像质量。形成的仿生复眼成像原型系统相当紧凑,重量仅为121 g,体积为34 mm×44 mm×80 mm,视场为120°×120°。该系统在军事,医疗和工程应用中具有巨大的潜力和价值。并在制作的仿生曲面复眼成像系统上进行相关的光学性能测试。结果表明可以实现良好的图像质量。形成的仿生复眼成像原型系统相当紧凑,重量仅为121 g,体积为34 mm×44 mm×80 mm,视场为120°×120°。该系统在军事,医疗和工程应用中具有巨大的潜力和价值。
